INFORMATICS 7.1.1
1. What is a Data Warehouse?A Data Warehouse is a collection of data marts representing historical
data from different operational data source (OLTP). The data from these OLTP are structured and optimized for querying and data analysis in a Data Warehouse.
2. What is a Data mart?A Data Mart is a subset of a data warehouse that can provide data for
reporting and analysis on a section, unit or a department like Sales Dept, HR Dept, etc. The Data Mart are sometimes also called as HPQS (Higher Performance Query Structure).
3. What is OLAP?OLAP stands for Online Analytical Processing. It uses database tables
(Fact and Dimension tables) to enable multidimensional viewing, analysis and querying of large amount of data.
4. What is OLTP?OLTP stands for Online Transaction Processing Except data warehouse
databases the other databases are OLTPs. These OLTP uses normalized schema structure. These OLTP databases are designed for recording the daily operations and transactions of a business.
5. What are Dimensions?Dimensions are categories by which summarized data can be viewed. For
example a profit Fact table can be viewed by a time dimension.
6. What are Confirmed Dimensions?The Dimensions which are reusable and fixed in nature Example
customer, time, geography dimensions.
7. What are Fact Tables?
1
A Fact Table is a table that contains summarized numerical (facts) and historical data. This Fact Table has a foreign key-primary key relation with a dimension table. The Fact Table maintains the information in 3rd normal form.
A star schema is defined is defined as a logical database design in which there will be a centrally located fact table which is surrounded by at least one or more dimension tables. This design is best suited for Data Warehouse or Data Mart.
8. What are the types of Facts?The types of Facts are as follows.1. Additive Facts: A Fact which can be summed up for any of the
dimension available in the fact table.2. Semi-Additive Facts: A Fact which can be summed up to a few
dimensions and not for all dimensions available in the fact table.3. Non-Additive Fact: A Fact which cannot be summed up for any of the
dimensions available in the fact table.
9. What are the types of Fact Tables?The types of Fact Tables are:
1. Cumulative Fact Table: This type of fact tables generally describes what was happened over the period of time. They contain additive facts.
2. Snapshot Fact Table: This type of fact table deals with the particular period of time. They contain non-additive and semi-additive facts.
10. What is Grain of Fact?The Grain of Fact is defined as the level at which the fact information is
stored in a fact table. This is also called as Fact Granularity or Fact Event Level.11. What is Factless Fact table?
The Fact Table which does not contains facts is called as Fact Table. Generally when we need to combine two data marts, then one data mart will have a fact less fact table and other one with common fact table.
12. What are Measures?Measures are numeric data based on columns in a fact table.
13. What are Cubes?Cubes are data processing units composed of fact tables and dimensions
from the data warehouse. They provided multidimensional analysis.
14. What are Virtual Cubes?These are combination of one or more real cubes and require no disk
space to store them. They store only definition and not the data.
15. What is a Star schema design?A Star schema is defined as a logical database design in which there will
be a centrally located fact table which is surrounded by at least one or more dimension tables. This design is best suited for Data Warehouse or Data Mart.
16. What is Snow Flake schema Design?
2
In a Snow Flake design the dimension table (de-normalized table) will be further divided into one or more dimensions (normalized tables) to organize the information in a better structural format. To design snow flake we should first design star schema design.
17. What is Operational Data Store [ODS] ?It is a collection of integrated databases designed to support operational
monitoring. Unlike the OLTP databases, the data in the ODS are integrated, subject oriented and enterprise wide data.

properties.
140. What is a aggregator cache in aggregate transformation?The aggregator transformation stores the data in the aggregator cache
until it completes aggregate calculations.
141. What is data cache and Index cache?When you use aggregator transformation in your mapping then
Informatica server creates Data and Index cache in memory to process the transformation.
142. What is a Mapping Variable?A Mapping Variable represents a value that can change throughout the
session. The Informatica server saves the value of mapping variable in repository in the send of the session and uses it for the next session run.
143. In which scenario does the Update Strategy Transformation is best suited?
Within a session: When you configure a session, you can instruct the Informatica server to either treat all records in same way (treat all as insert/treat all as update/treat all as update) or use instructions coded into the session to flag records for different database operations.
Within a Mapping: Within a mapping, you use the update strategy transformation to flag records for insert, update or reject.
144. What are the types of mappings in Getting Started Wizard?1. Simple pass through mapping: loads a slowly growing fact or dimension
table be inserting new rows. Use this map to loading new data into it.
17
2. Slowly growing target: Loads a slowly growing fact or dimension table be inserting new rows. Use this map to load new data without disturbing the existing data.
145. How can you recognize whether or not the data is added in the table in Type – II dimension?
1. By version number2. By flag value3. By effective date range
146. Why you use Repository connectivity?When you edit or schedule the session each time, Informatica server
directly communicates the repository to check whether or not the session and users are valid.
147. What are the data movement modes in Informatica?The data movement modes determines how Informatica server handles the
character data. There are two types of data movement modes:1. ASCII mode 2. Uni code mode
148. Can you copy the session to a different folder or Repository?Yes. By using the copy session wizard you can copy a session in a
different folder or Repository. But first you should copy the mapping of that session before you copy session.
149. What is the difference between partitioning of relational target and partitioning of file target?
If you partition a session with a relational target Informatica server creates multiple connections to the target database to write target data concurrently. If you partition a session with file target the Informatica server create one target file for each partition.
150. What are the Transformations that restrict the partition of sessions?1. Advanced External Transformation2. External Procedure Transformation3. Aggregator Transformation4. Joiner Transformation5. Normalizer Transformation6. XML Targets
151. What is a Power Center Repository?The Power Center Repository allows you to share metadata across
repositories to create a data mart domain. In a data mart domain, you can create a single global repository to store metadata used across an enterprise and a number of local repositories to share the global metadata as needed.

necessary for impromptu to access and retrieve information from a relational database. A Catalog does not store data but contains metadata information like what database to access, where the database is stored, and how the tables in the catalog are joined. There are four types of Catalogs:
1. Personal Catalog2. Secured Catalog3. Shared Catalog4. Distributed Catalog
12. What is a Personal Catalog?A Personal Catalog is intended for the small business owner who wants to
maintain a data such as personal information, customer list etc. use Personal Catalog if you are the only person using the catalog and you are using the Administrator version of Impromptu.
13. What is Secured Catalog?A Secured Catalog is intended for users who do not need or want to
create or edit their own reports. The users cannot change this catalog in any way. The Secured catalog is useful for users who are not familiar with Impromptu and just want to analyze the data in the pre defined reports.
14. What is Shared Catalog?A Shared Catalog is intended for a workgroup or company were several
users need to create and edit their own reports. The Shared Catalog is ideal in a LAN environment where the catalog can be stored in a central and shared drive and accessed by all the users.
15. What is Distributed Catalog?The Distributed Catalog is intended for a workgroup or company where
several users need to create and edit their own reports and change the catalog content and work offline with Impromptu. The Distributed Catalog is ideal is the users wants to work with the Impromptu offline.
16. What is Drill Through?Drill through is an action that enables Impromptu PowerPlay and Scenario
users to view transactions level details in an Impromptu report. You can setup a Drill Through for any cell in Impromptu, any value in PowerPlay or any node in the Scenario’s tree view. You can navigate through a set of associated reports.

Unlike an automatic association, the Fixed Association remains the same when you move it to a new location.
20
19. What is a Hot File?A separate local data table that can be added to your catalog or used in
the report as a data source and as if it is a regular database table. A Hot File can be joined either with a database table or with another Hot File itself.

and the prompts that are created in the report environment are called as Non reusable prompts.
24. What are different data sources to generate the reports?The different data source to generate the reports are: 1. Catalog2. Snapshot3. Hot File4. Thumbnail
25. What is a Snapshot?A permanent local copy of the report data which can be even manipulated
later without connecting to the original database. You cannot add a data item into the snapshot. Best suitable when you are working in a disconnected network.
26. What is a Thumbnail?A temporary data file with a restricted number of rows best suited for
testing the report. You can add a data item into the thumbnail. The Thumbnail will be deleted when you close the entire application. 27. When “Loop – Exception” is occurred and how it is resolved?
Is two tables share a single lookup table then the “Loop – Exception” is occurred. To resolve the Loop exception do one of the following actions:
1. Remove one or more join.2. Create an Alias Table.3. Remove that table form the catalog4. Leave the join structure as it is.
28. When “Isolated Table – Exception” is occurred and how it is resolved?If a table is not joined to other table then the “Isolated Table” exception
occurs. To resolve this do one of the following:1. Add a join between two table groups to create a Spanning tree.2. Leave the join structure as it is.
21
29. What are objects that exists in the catalog?A catalog contains the following types of objects:1. Filters 2. Expressions3. Prompts4. Attributes / Columns

49. What is a Calculation?A Calculation computes a new data based on existing data items.
50. What is a Conditional Statements?The Conditional statements are often used in calculated columns to
highlight general categories of data. You use IF…THEN …ELSE constructs to create the Conditional Statements. Most of the conditional statements will be processed locally.
51. What is a Summarized Data?The Summarized Data includes the type of summary to perform on any
data item. We use Summarized data to see a roll-up view of the data and to perform exploratory analysis of the data.
52. What is Summary Association?When you add a summary to a query, the Impromptu will have an
automatic association to that summary by default that is the summary which we have done will be associated with an data item. There are two types of Summary Associations:
1. Position Dependent: A summary with an automatic association changes value depending on its position in the report.
2. Position Independent: A summary with a fixed association has a value that does not change when you move it form one place to another.
24
53. What is a Crosstab Report?A Crosstab report summarize information in tabular format showing a
value at the intersection point of each row and column. In a Crosstab report we have Rows, Columns and Cells.
54. What is a Crosstab Dimension?The Crosstab Dimensions are the qualitative values of a data item along
the top of the Crosstab report. For example if the “Country” data item is show in crosstab report then the country names are the crosstab dimensions.
55. What are Functions?Functions are commands that take one or more values, perform an
operation and return a result. Functions can be included in calculations to perform data manipulations that would otherwise be impossible to do. The functions can use any of the following Impromptu’s only supported data types:
1. numeric2. character3. data4. data – time5. time6. interval

There are three options available to set the scope of data. They are :1. Single row of data2. Data in the group3. All Data
58. Can you use multiple database to create catalog?Yes, in Cognos EP 7 there are two ways to access data from multiple
database to create a catalog1. By Staging Database2. By Hotfiles
59. What is Staging Database?Combining two different database (say data marts) and integrating into a
single database to create a catalog.
60. What is System of Report?
25
The System of Report contains multiple queries and multiple report layouts. We use the system of report to provide:
To navigate from summary level information – details through Sub reports
Report-to-Report drill through feature.
61. What are ideal circumstances to use Sub Reports and Drill Reports?
Report Type Best Used WhenSub Report When you want single or multiple
queries in a single report.When you want detail and summary information in the same report.When you are advanced user.
Drill-Through Report When you want multiple queries in a report, or a series of reportsWhen you want detail and summary information in different reports.When you a beginner or intermediate user.
62. When to use Limited Local Processing?Use Limited Local Processing settings when:

commonly for BLOB data type columns.26
66. What is a Hotfile and what are the uses?A Hotfile is a file sequential file (not indexed) that holds from a report and
acts like a separate local database table. The Hotfile must be accessed from a catalog. The Hotfile is saved with .IMS extension. The following are the uses of Hotfile:
To compare historical values To access subsets of large tables To speed up processing To access data from more than one database to create a
catalog.

Public Folders: Public Folders can be viewed by many users.My Folders: Personal Folders that you can organize according to your
preferences.
6) What are the uses of Query Studio?1. Create ad hoc reports that can be viewed by others.2. Customize ad hoc reports that have been saved.3. Compare and analyze data.The corporate data available to you is stored in a package that has been created by the Report Net administrator and published to Cognos Connection.
7) What is a Package? Package is interfacing between the data base and End user nothing but
Business user.Packages use corporate business rules to define and group the data to be
used for business reporting.
8) How can you create Ad hoc reports?The administrator previously creates a package in Framework Manager
and publish to a location in the Cognos Connection portal to which you have access. With that we can use in our ad hoc reports.
9) How can you view the data from existing report?1. From the report viewer.2. While editing of the report in Query Studio.
10) What is prompt?The prompt is dynamic filter, which can extract the data from existing
report.
31
The prompts are very faster and easier than repeatedly changing the filter.
11) How can you add the calculated data to a report?1. Summarize existing detail values predefined summary functions (such
as sum, avg)2. Create new report items using data from existing report items.3. Use model calculations provided in the package.
12) What is Frame Work Manager?Frame work manager is an application that runs in Microsoft windows and
provides a model development environment. Frame work manager allows you to develop the Meta data models called projects. Frame work manager provides Meta data model development environment to develop the business packages as per the business requirements.
In frame work Manager, you have to interact with a project, with contains:
A. A modelB. Name spacesC. Data sourcesD. Parameter mapsE. PackagesF. FolderG. Query subjectH. Query itemI. Relation ship
12) What are the types of Query Subjects?1. Default data source query subjects2. Model Query Subjects3. Stored Query subjects.

with local Languages that the default value is ‘EN’
15) What is physical layer?The Physical layer provides the physical query layer and is made
up primarily of data source and stored procedure query subjects. It acts as the foundation for the presentation layer.
16) What is Presentation layer?The Presentation layer makes it easier for report authors to find and
understand their data. The Presentation layer is made up primarily of model query subjects that you create.
17) Define function set:A function set is a collection of vendor specific database.
32
The Expression editor lists the function sets for all available vendors. However, you can restrict the function sets, so that it lists only the vendors that you want to use in your project.
18) What is a Model?A model in Frame work manager is a business presentation of the
structure of the data from one or more databases.Or
A model is a set of related query subjects and other objects.
19) Explain about Data Source Query Subject?Data Source query subjects contain SQL statements the directly reference
data in a single data source. Frame work manager automatically creates a data source query subject for each table and view that you import into model.
Example When we import the product the table from Go sales sample database, Frame work manager creates a query subject using the following statements.
“select * from [go sales].product”
20) How can you edit the data source query subject?
i. Apply or embed a filterii. Apply or embed a calculationiii. Insert a Macroiv. Insert a data source reference.v. Change the SQL type.vi. Change how SQL is generated.
These all are we can find it in “Edit definition window”.
21) What are the types of SQL?SQL is the industry language for creating, updating and querying relational
data base management system. Types of SQL.1. Cognos SQL2. Native SQL3. Pass-through SQL.
1 Cognos SQL:By default Cognos Frame work manager uses Cognos SQL to create and
edit Query subjects.
Advantages:1. Can contain metadata from multiple data sources.2. Have fewer database restrictions3. Interact more effectively with Cognos applications.
Disadvantages:You can not enter nonstandard SQL.
2 Native SQL:
33
Native SQL is the SQL, the data source uses, such as Oracle SQL, but you cannot uses Native SQL in a query subject that references more than one data source in the project.
Advantages:1. Performance is optimized across all related query subjects.2. You can use SQL that is specific to your database.
Disadvantages:1. You cannot use SQL that the data source does not support for
sub queries.2. The query subject may not work on different database type.
3 Pass-Through SQL:Pass-Through SQL lets you use native SQL without any of the restrictions
the data source imposes on sub queries.
Advantages:1. You can enter any SQL supported by the database.
Disadvantages:1. There is no opportunity for Frame work manager to
automatically optimize performance. The SQL may not work on a different data source.
22) How can you restrict the tables retrieved by a query?By setting governors we can restrict the tables. tables.
23) What is the security filter?A security filter controls the data that is shown to report authors when they
set up Their reports.
24) Is there any impact if the package republish with frame work manager to Report Net server?
No, no reports are impacted, if republish the package.
25) Explain Stitch Queries?In the event of cross fact table queries, ReportNet will send two separate
Queries to the data source, one for each fact table. It will retrieve two record sets, which will be merged locally by stitching together the common dimensional records in each record set.
26) What are Query Processing Types?There are two types of query processing.
1. Limited Local: The database server does as much of the SQL processing and Execution as possible. However, some reports or report sections use local SQL processing.
2. Database only: The database server does all the SQL processing and execution with the exception of tasks not supported by the database. An error appears if any reports of report sections require local SQL processing.
34
27) How can you create the query subject?We can create the query subjects through models, data sources, and
stored procedures.
28) What is parameter map?The parameter maps are key value phase, which are used for working
with local Language that The default value is ‘EN’.
29) What is a Macro?To change the SQL syntax conditionally is called macro.
30) What are the types of filters?In framework manager we can create two types of filters.
1. Model filters.2. Query filters.
Filters: In the report studio we can find two types if filters.1. Tabular filter2. Summary filters
1. Tabular filters: Tabular filters are two typesA. Summary filtersB. Detailed filters
2. Grouped filters.
31) What is the use of Short cuts?To organize the information that you use regularly is called short cuts.
32) What is the use to disable entries in Cognos connection?We can disable the entries, which was created by you, to prevent other
users from accessing it. Disabling it. Disabling is useful when you want to perform maintance operations. When you disable a folder, everything in the folders is disabled as well.
33) What is Query Studio?Query Studio is the adhoc querying tool for ReportNet.
34) Which component will create a package?The package will be created by the Report Net administrator and will
publish to Cognos connections.
35) What are the report items?The items, which are added from the package to your report are called
report items.
36) How it appears a project in Frame work manager?A frame work manager project appears as a folder that contains a project
file (.cpf) and the specific XML files that define the project.
37) What is the difference between the Frame work manager model and the adhoc query authors?
35
Frame Work Manager model Adhoc query authorsWith in Frame Work Manager, modelers interact with a development model, which exists within the XML based project located on the file system.
A report or adhoc query author interacts with a run-time version of the Framework Manager model. This model appears as the set of published metadata on which reports and queries are based.
38) When the default data source query subject is created?During the initial metadata import operation, a default data source query
subject is created for each object you select (for example table) and creates the default relationships between query subjects for you automatically.
39) What are phases the work flow process consists in Frame Work Manager?
The work flow process consists of the following phases:• Design and create project• Prepare Metadata• Prepare the Business View• Create and Manager Packages• Set Security• Publish• Manage the Project
40) How you set the security Frame work manager?
To set the security you have to set as:• Define access to packages.• Create Security filters• Define access to objects• Define package administration access.
41) What is a Physical Layer?The physical layer is a representation of the metadata as it appears in the
data source. Provides a foundation for the presentation layer. It is made up primarily of data source and stored procedure query subjects.
It is created import only the smallest number of objects required and to create calculations and filters that meet a wide range of business requirements.
42) What is Presentation Layer?The Presentation Layer is a modeled business view of the metadata from
the data source, facilitates report authoring and it is made up primarily of model query subjects and shortcuts.
43) The types of query processing?There are two types of query processing to choose from:
• Limited Local : The database server does as much of the SQL processing and execution as possible.
• Database Only : The database server does all the SQL processing and execution with the exception of tasks not supported by the database.
36
44) What are the Building Blocks in Frame work manager?The Query subjects are called Building Blocks in Frame work Manager.
45) What is usage property? And what are different setting to set usage property?
It identifies the intended use for the data represented by each query item.
It determines the aggregation rules of query items and calculations.
The different Usage property settings are: Identifies Fact Attribute Unknown
46) Can you edit the metadata in Frame Work Manager?Yes, We can edit the meta data in Frame work manager. And also we can
translate the metadata to a more convenient format, such as CSV or Unicode text.
47) What is parameter map and what it consists of?Parameter maps are similar to data source look-up tables.Each parameter map consists of two columns:
• Key (must be unique)• Value (Used for substitution)
48) What is session parameter?Session parameter is a variable, such as username, or a run Locale, that
Frame work manager associates with a session.
49) What is override value?The override value is to test the results that value returns. The override
value is valid only while you have the model open, and is not saved when you save the model. If no override value exists, Frame work manager uses the default value when it executes a query that contains a session parameter.
50) Where you can use the prompts?• The prompts where we can use:• Parameter maps• Session parameter• Stored procedure arguments• Expression, including filters, calculations and
relationships.
51) What is the use of prompt value?A prompt value can be used when user input is required for variables
beyond the report author’s control.The syntax is :?<prompt name>?
37
52) How can restrict the number of rows?By setting the Governors, you can restrict the number of tables retrieved
by a query as well as restrict the number of rows returned. You can also set time limits for query execution, as well as restrict character length on binary large objects (BLOBs).
53) What are security objects, Cognos namespace contains?The Cognos namespace contains security objects, which are
• Per-defined group or roles• User-defined groups or roles
54) What tasks do you perform to set the repository control?To set up repository, perform the following tasks:
• Create the repository• Set up the path to the repository• Configure a connection to the repository• Add the project to the repository
Once the repository connection has been established, you can modify or delete it through the connection manager.
55) What tasks will be done after creating of segment?You can create a segment so that you can:
• Organize a project according to organizational requirements, fro example, human resources, sales, and finance, or according to business rules.
• Distribute responsibility for the modeling process amongst multiple groups according to areas of expertise.
• Share and reuse project information to avoid duplication in a new folder.
56) What is a link? What are the uses from links?A link is a shortcut to an existing project, folder, or namespace.The uses from links are:
• Organize work across large projects.• Maintain consistency• Reuse information
57) What is use from the Dimensional Information?Dimensional information is used to associate attribute with levels to
ensure proper aggregation and avoid double counting or repeating values.“A confirmed dimension has relationships to more than one fact table”
58) What are the ReportNet Administration Roles?1. System Administrator: This is like super key, can access and modify
any object in the content store.2. Directory Administrator: This can administer the contents of
namespaces.3. Report Administrator: This can administer the public content.4. Server Administrator: Can administer services and dispatchers.
38
59) When a report cannot be viewed?A report cannot be viewed at the time it is run when it:1. It runs later2. has multiple formats or languages3. has a delivery method of save, print or email4. is a burst report
60) How can you distribute the reports?You can distribute reports to other users to share information with the. You can distribute reports by: 1. Saving them where other users can access them2. sending them to other users by email3. printing them
61) What is the use from a Burst Report?1. Use bursting to run a report once and divide the results for distribution
to multiple recipients.2. Each recipient will only view a subset of the data3. Burst reports can be distributed by email, saved to a directory, or both.
62) What are the distribution lists contain?The Distribution lists contain a collection of users, groups, roles, contacts,
or other distribution lists.If a recipient is not part of the Cognos security system, you can create
contact information for this person, such as name and email address.

• Web server• Applications• Data
101) What is the affinity?Affinity is between request and server ensures that requests are routed to
an appropriate computer for execution.
102) Can you edit an existing report?Yes, we edit the existing report by inserting additional report items, or you
can focus on specific data by removing unnecessary report items, or adding filters.
103) What is the use of schedule?The schedule allows you to run a report at a later time or run it on a
recurring basis (for example, every Monday at 2pm).
104) How can you configure ReportNet to perform Bursting?To burst report data, you have to configure:
Specify burst repents from a data source Create the report and specify a burst key in Report
Studio Set burst options in Report Studio Run the report with bursting enabled in Cognos
Connection.105) What is a burst key?
The Burst key is who the intended recipients are and by what method you intend to distribute the reports in the ReportNet.
44

108) What are the information do you need to create burst table?To create a Burst table to map recipients or groups of recipients to specific
data that they are allowed to see. Unique Identifier List of Recipients Data item to Burst on
109) What is the impact of changes to row or columns of the burst table?Burst reports that are affected by changes to the burst table may fail when
they are run.
110) How can you set the burst options?Ensure that the report contains the query item you intend to burst the
report on and group it.Set the following burst options:1. Burst key : defines how the data should be filtered and divided2. Burst recipient : determines who receives the subset of data
111) The consideration of Burst to Email Recipients?To supply email addresses when you burst a report to email recipients,
you can either:1. reference the email address for each user that is stored in your
authentication source when bursting to directories2. supply the email address in the report itself by creating a calculated
filed3. reference the appropriate burst table column
112) What is the use from page structure view?1. Locating hard – to – objects in a report2. quickly moving objects from one area of a page to another3. Modifying object properties.
113) How can you add a layout to Report Specification?The layout section of a report specification determines how the data is
displayed on the pages of the report.A report requires at least one layout, but may have more. You can add
multiple layouts to accommodate different languages.The layout section of the report specification consists of:
45
• Pages• Layout Objects
114) What are the tool bar objects (explorers)?The objects available in the toolbox are different depending on which
explorer you have open.Those are:
1. Page explorer tool box2. Query explorer tool box3. Query explorer tool box
115) Can you create a custom toolbox object?Yes, To create a new toolbox object, you must add it to the Standard
components.xml file, and then reference it from the Toolbox.xml file.You can add the object reference to one of the following sections of the

Business Objects 6.1b
1) What is Web intelligence?Webintelligence is a single tool for understanding and controlling the
business tasks. It enables you to access, analyze and share corporate data over internets and extranets for RDBMS AND OLAP servers. To access Webintelligence we log into the INFOVIEW portal via Internet Explorer.
2) What is Universe?The special semantic layer that isolates you from the technical issues of
the database is called as Universe. The Universes are created by a Universe designer using Business Objects Designer software.
3) Explain INFOVIEW Portal?The INFOVIEW portal is organized into the following parts:
1. Toolbar2. Page content
Toolbar :- The INFOVIEW Toolbar contains the following links to the following pages.
1. Home Page2. My Infoview Page3. Optional Page4. Help Page5. Logout Page
Page Content :- The Page Content contains the following options:1. Corporate Documents2. Search3. Personal Documents4. Inbox Documents5. New Documents6. Add a Document7. Scheduled Documents
4) What are the documents you can access from Infoview?INFOVIEW allows you to access the corporate documents from three
storage areas like:1. Corporate Documents2. Personal Documents3. Inbox Documents
5) What are the Document categories in INFOVIEW?Categories are a way of organizing documents in INFOVIEW portal. A
Category displays only the documents that have been assigned to it. There are two kinds of Categories:
1. Corporate Category2. Personal Category
6) What are the formats supported for Business Objects documents?You can view Business Objects documents in the following formats:
1. HTML2. PDF
49
3. Enhanced Document Format4. Business Objects Format
7) What are the formats supported for Web intelligence documents?You can view Web intelligence documents in the following formats:1. HTML2. HTML(Interactive)3. PDF
8) Explain the query process in Webintelligence?Using the Webintelligence Report Panel, you construct a business
question that represents the information you need. This question is sent in the form of a query to the Business Object’s server where the data and send it back to the Webintelligence in the form of a Data Provider.
The contents of the Data Provider are then projected into a Webintelligence report in the form of tables, crosstabs and charts etc.
9) What is object? What are the types of Objects in Universe?Objects are elements in a Business Objects that correspond to a selection
of data in the database. There are three types of Objects exists in the Universe.1. Dimension2. Measure 3. Detail
10) What are the Report Panels exits in Webintelligence?Webintelligence provides two types of Report Panels:
1. Java report Panel: Enables you to create sophisticated documents containing multiple reports, tables and charts. You can create complex filters, custom formulas and highly formatted documents in Java Report Panel.
2. HTML Report Panel: Enables you to create simple reports helped by wizard – like style tabs. You can apply simple filters and standard calculations to a report in HTML Report Panel.
11) What is Report Manager in Webintelligence?The Report Manager is displayed to the left hand side of the
Webintelligence Java Report Panel. We use this Report Panel to: Manage all the objects and variables in the document (Data Tab). Change the type of blocks in the report (Templates Tab). Format the properties of the report and its contents. (Properties
Tab) Navigate through the documents (Map Tab).
The Report Manager is made up of four tabs:1. Data Tab2. Templates Tab3. Properties Tab4. Map Tab
12) What is Query Filter? What are the advantages of Query Filter?To restrict a query means you limit that amount of data that is retrieved
from the data source and returned to your Webintelligence reports. The Query Filters retrieve a sub-set of the available data, based on the definition of the query filter. Restricting the query in this way ensures that you retrieve only the
50
data that interests you. Through query filter, you can minimize the quantity of data returned by the report and thus reduces the time required to create and refresh the document over the network. The query Filters are made up of three parts:
1. Object2. Operand3. Operator.
The following are the advantages of the Query Filters: You retrieve only the data you need to answer a specific business
question. You hide data you don’t want specific users to see when they
access the document. You minimize the quantity of data returned to the document to
optimize performance.
13) What are the types of Query Filters that you use in Webintelligence?There are four types of Query Filter you use in Web intelligence:
1. Predefined Filters2. Single and Multi – value Filters3. Prompted Filters4. Complex Filters
14) What are the types of tables available in web intelligence?Web intelligence provides four different types of tables:
1. Vertical Table2. Horizontal of Financial Table3. Cross tab4. Form
15) What are the basic chart types available in web intelligence?Web intelligence provides the following basic types of Charts
1. Bar charts2. Line charts3. Area charts4. Pie charts5. Radar, Polar and Scatter Charts
16) What are the Reporting Tools available in the Report Panel Toolbar?The following are the Reporting Tools available from the Report Panel
23) What is Scope of Analysis?The Scope of Analysis for a query is extra data you can retrieve from the
database to give more details on the data returned by each of the objects in a query. This extra data does not appear in the initial document results, but you can pull this data at any time into the report from the data cube. In the Universe, the Scope of Analysis corresponds to the hierarchical levels below the object selected for a query.
24) What is Drill in Webintelligence documents?When we talk of drill mode in Webintelligence, we often refer to two
activities that are related:1. Setting up a Webintelligence or Business Object document so that you
and other users can analyze the reports in drill mode.2. Viewing the document in drill mode, either in Webintelligence Report
Panel or in Info View and analyze the data at different levels of detail.
25) How many ways you can share Webintelligence and BusinessObject documents?
You can share Webintelligence and BusinessObject documents in three ways:
1. Send a document to another user or group of users2. Schedule documents to be refreshed and sent automatically but using
the Broadcast Agent3. Save documents as files on your computer in PDF and Excel format.
26) What are the advantages using BusinessObjects?The advantages of using BusinessObjects are:1. Users construct queries via objects named in their own business
terminology using drag and drop technology2. User queries are sent directly to the target database without day to day
intervention from the MIS department.3. Users can analyze and format the data locally.
27) What is the Universe development process?The flowing are the phases involved in development of Universe:1. Prepare2. Analyze3. Plan4. Implement5. Test6. Deploy7. EvolveNote: Universe design should always be driven primarily by user requirements and not the data source structure.
28) What are Parameters?A Universe is built within a file that has a .unv extension. As part of the
process of creating the .unv file you have to set certain parameters. These
53
parameters are the name of the Universe to be contained within the file, a description of it and a connection to the target database that the Universe provides a front end.
29) What are the tabs of Universe Parameter dialog box?The sub tabs of the Universe parameter are:1. Definition2. Summary3. Strategies4. Controls5. SQL6. Links
30) Explain Joins in BusinessObjects?A Join is a condition that restricts the result set of a multi-relational query.
The BusinessObject supports the following Joins:1. Equi-join2. Quter join3. Theta Join4. Self Join
31) What is Theta Join?A Theta Join contains an expression that is based on something other
than equality.
32) What is Cardinality?Cardinality is the term used for expressing the relationship between tables
based on joins. Cardinality is used by BusinessObject to provide enough information to detect and resolve loops. It can also be a useful aid to designer in understanding database structures.
33) What is a Dimension?Dimensions are used to infer columns, constants, calculations or a
concatenation therof in the select clause of the select statement but not aggregates.
34) What is Measure?Measures are used to provide dynamic statistical information in a
BusinessObject query. The value of the statistic is dependent on the dimension and detail objects in the query.
A Measure object is created by using aggregate functions like Sum, Count, Average, Maximum and Minimum. Measure objects are very flexible because they are semantically dynamic. When a BusinessObjects Query is made which includes a measure it automatically infers a Group By clause in the select statement.
35) What is the SQL rule in Inference of the Group By clause?If the Select clause line contains an aggregate, everything outside of that
aggregate in the clause must also appear in the Group By clause.
36) What are the elements to test the Dimension object?
54
The following are the elements to test the Dimension object:1. Check objects exist2. Check inferred SQL3. Check query results4. Repeat with other dimensions5. Make a query with a minimum of two dimensions and a measure6. Check projection with Slice & Dice
37) What is a Loop?A Loop is caused by asset of joins which defines a closed path through a
set of tables in the structures.
38) What is the problem caused by Loop?The joins in the structure are used to create the where clause in the
inferred SQL of a query. Their purpose is to restrict the data that is returned by the query. In a Loop, the joins will apply more restrictions than the designer intended and the data returned will be incorrect.
39) How to resolve the Loops?There are automatic routines built in the Designer module which can be
used to identify and resolve the Loops. They are:1. Using Aliases2. Using Contexts
Note: IT is very important that all cardinalities are set correctly for the loop detection and resolution routines to work correctly.
40) How you resolve the Loop by using context?Generally in normalized dimensions Aliases are not suitable resolve loops
and in such situation we use Context. A Context is a list of joins which identify a path through the structure. Contexts are set to identify alternative routes in the universe structure. Contexts identify joins which are compatible within the same Select statement.
41) What is a Shortcut Join?A Shortcut Join is a join that links two tables together but bypasses
intervening tables that exist in the universe. This is used when designing universes where it is possible in certain circumstances to make the inferred SQL more efficient.
42) What is a Self Join and how it is resolved?A Self Join from one column of a table to another column of the same
table. We can resolve the Self Joins by inserting Aliases.
43) What is Chasm Trap and how to resolve it?Chasm Trap is the problem that is inherent is SQL which is caused by the
order in which the elements of Select statement is processed. The Chasm Trap can occur when tow joins from many to one converge on a single table. Unlike Loops, chasm Trap returns too many rows i.e. when you have a many-one-many relationship for tables in the from clause the resulting logical table will produce something similar to Cartesian product, this is the reason of the Chasm Trap effect.
55
To resolve Chasm Trap we use1. Alter SQL parameter for the Universe2. Inserting Contexts
According to the first option, set SQL parameters option in Universe Parameter dialog box i.e. in the Universe Parameter dialog box, select the SQL tab and there select the option called “Multiple SQL statements for each measure”.
Note: Always use contexts to resolve Chasm Traps
44) What is Fan Traps and how to resolve it?Fan Trap is the problem that is inherent in SQL which is caused by the
order in which the elements of Select statement is processed. The Fan Trap can occur when there is “one to many” join to a table that fans out into another “one to many” join to another table. Unlike Loops, Fan Trap returns too many rows i.e. when you have a one-to-many relationship for tables in the From clause the resulting logical table will produce something similar to Cartesian product, this is the reason of the Fan Trap effect.
To resolve Fan Trap we use1. Alter SQL parameter for the Universe2. Use combination of Context and Aliases.
Note: Always use combination of context and aliases to resolve Fan Traps
45) How many @ Functions are there?The following the @ Functions available:
46) What is a List of Values?List of Values is a list of the distinct values from the column to which the
object refers. A LOV is used on the operand side of a condition in the query panel of the user module.
47) When to use the List of Values?There are three things that a universe designer should bear in mind when
deciding whether to associate a LOV to an object:1. Because a LOV is based on a SELECT DISTINCT query which is fired
at the target DB, associating a LOV will have implications for the efficiency of BusinessObjects.
2. The only purpose for creating a LOV is to assist the end user in choosing an operand value for a condition. If the LOV does not do this, there is no point in associating it with the object.
3. Unless the LOV is based on a personal file and not a query, the list will only hold values that exist within the database.
48) What is a Hierarchy?A Hierarchy is an ordered series of related Dimensions objects, which are
used for multidimensional analysis. For example, a geographical hierarchy could group together Dimension objects such as County, Region and City.
56
49) What is a Multidimensional Analysis?Multidimensional analysis is a technique for manipulating data so that it
can be viewed from different perspective and at different levels of detail.
50) What is Aggregate Awareness?Some databases have Summary tables which contain figures aggregated
to a high level. These are used to speed up queries which contain statistics. The Aggregate Awareness is the BusinessObjects process by which these higher level aggregates are incorporated into a universe.
51) What is the procedure of applying Aggregate Awareness?The following are the procedure for applying Aggregate Awareness:1. Insert the summary Table in the Universe structure, set joins and
cardinality.2. Set the contexts.3. Redefine objects using @Aggregate Aware.4. Define incompatible objects using Aggregate navigation.Note: Step 1 and 2 are not required if the summary table does not contain
foreign keys.
52) What is the procedure for distributing a universe in Work Group?The procedures for distributing a universe in Work Group are as follows:1. Make a copy of the universe file and place it on the file server.2. Ensure an appropriate driver exists on the server and that the universe
connection is of shared type.3. Set password protection if required.4. Inform the users about the location of the .unv file containing the
universe.
53) Explain the Repository of the BusinessObjects?The Repository of the BusinessObjects is a database consists of:1. Universe Domain – consists of 24 database tables used to store
universes.2. Document Domain – consists of database table used to store files
including BusinessObjects documents (.rep). List of Value files (.lov), etc.
3. Security Domain – consists of 25 database tables used to store BusinessObjects users and their permissions.
54) Why should we link universes?One possible reason for linking universes is where have a number of
universes, each of which contains the same core set of objects. By creating each universe as a separate entity you are effectively coding the same objects several times over. By linking you could avoid this.
55) What is Business Intelligence?It is a broad category of application programs and technologies by using
which users can gather, store and analyze the business information for multidimensional analysis. The Business Intelligence is accomplished through:
1. OLAP Tools2. Query and Reporting
57
3. Data Mining4. Statistical Forecast Analysis.
56) What is Repository?A Repository is a centrally storage place where the Meta Data definitions
are being stored for each report. Supervisor module is responsible for creating Repository with 50 database objects (tables) with 3 basic domains, Security Domain – 25 tables, Universe Domain – 1 table and Document Domain – 24 tables.
57) What are the User Profiles in BusinessObjects?The following are the User Profiles in BusinessObjects:1. General Supervisor2. Supervisor3. Designer4. Supervisor – Designer5. User (Normal user)6. Versatile
58) What is a Bomain.Key?a file that contains the address of the repository’s security domain. This
file must be distributed to all users who will access the BusinessObject repository to share universes and documents. By default the Bomain.Key file will be placed in “BusinessObjects\LocData folder.
59) What is a Class?A class is defined as a logical grouping of objects defined in the universe.
Generally the name of the class reflects the type of object it contains. A class in further sub divided into sub classes.
60) What is a Object?An object is the most refined component in the universe. It maps to the
data or the derivation of the data in the database. There are three types of objects we can create in BusinessObjects:
61) What is a Prompt?A Prompt is a dynamic filter which allows the end users to feed the
condition at the run time and displays the results on the report based on the values fed in the prompt. In BusinessObject the prompt is created by using “@Prompt”.
@Prompt(p1, p2, p3, p4, p5)Where p1 : name of the prompt
p2 : data typep3 : LOV pointerp4 : Mono or Multip5 : Free or constraint
62) What are Blocks?
58
In Webintelligence Blocks represents tables, charts, cross tabs and forms in which the business information is displayed. A Report Manager manages the data to be represented in a different formats called as Blocks and allows to set the properties of Blocks.
