Premiere Products

• Distributor of appliances, housewares, and sporting goods

• Uses spreadsheet software to maintain important data

• Recent growth has made the spreadsheet approach problematic:– Redundancy– Difficulty accessing data– Limited security

– Size limitations

query to answer questions 2, 4, 6, 8, 14, 15 for Premiere Products and questions 5, 7, 12, 19 for Henry Books.

• Chapter 4 pp 150-152]: Use ACCESS to write the appropriate SQL query to answer questions 2, 4, 7 for Premiere Products and questions 2, 4, 10 for Henry Books (1 bonus question included).

• NOTE: USE the copy of the Premiere Products and Henry Books database from the end of Chapter 1 [the version you had BEFORE starting Exercise 2].

• Turn-in printouts of the datasheet, or report and the related query (as appropriate), which shows the answer [datasheet view, table view, etc.] to the query posed along with the SQL query that produced the result. Screen prints may be used, if necessary.

Exercise #4

• Due: Feb 23 for full credit, Mar 1 for 50% credit• Points: 20 points• Pratt & Adamski (End of Chapters 5 & 6)

• Assignments must have cover sheet with your name. • Chapter 5 [pp 174-175]: Answer questions 1, 2, 3 for

Premiere Products and questions 2, 4 for Henry Books. Omit 4NF, answer the questions for 3NF.

• Chapter 6 pp [221-222]: Answer questions 2, 4 for Premiere Products and questions 1, 2, 3 for Henry Books. Turn in ERD and copies of new tables and attributes. (Alternatively, use DBDL.)

Exercise #5• Due: Mar 15• Points: 10 points• Pratt & Adamski: Premiere Products [PP] and Henry Books [HB] Databases

• Use ACCESS, PP, and HB databases.• Redesign both PP and HB databases as they would be for a data

warehouse as described in Adamson & Venerable [Chapters 1 & 2] and Marakas [Chapters 1 & 2]. Use the Star diagram as the basis for their design. Be sure to include a meaningful Time dimension table. You are not asked to implement the DBs, i.e., the tables may be completely empty.

• Turn-in printouts of the REVISED relationship diagrams, i.e., the Star Diagrams, for both databases (deliverable 1)

• Turn in a list of 5 managerial questions for each case, that could be addressed with the help of the star schema (deliverable 2)

• On a separate page(s), clearly identify for each database: Fact tables, dimension tables, primary keys, foreign keys, alternate keys, etc. Use relational notation from Pratt & Adamski (deliverable 3).

• Indicate the normal form [1NF, 2NF, 3NF, etc.] of each table (deliv. 4)• NOTE: Use the ORIGINAL copy of the Premiere Products and Henry

Books databases for this assignment.

Exercise #6•Due: Mar 29•Points: 20 points•Pratt & Adamski: Premiere Products and Henry Books [PP & HB]. Use the original DB files. Three deliverables (d1-d3) for each DB.

•1. Generate the SQL Code needed to create the fact tables for both the PP and HB databases. Turn in the SQL statements (d1) BEFORE the make-table conversion.

•2. Execute your SQL code and populate the fact tables. Turn in screen shots with the fact tables (d2) contents AFTER the make-table conversion.

•3. Generate the ACCESS ERDs for both PP and HB. Arrange the entities to minimize cross-over lines. Adjust the primary and foreign keys to conform with our original database models. Turn in screen shots of both star schemas (d3) in Access relationship view.

Exercise #7 [TEAM PROJECT] p. 1 of 3Due: April 5Points: 30 pointsPratt & Adamski: Premier Products Star Diagram

Assignments must have cover sheet (deliverable 1), table of contents (d2), and indicate the NAMES OF ALL TEAM MEMBERS and the TEAM NUMBER. Assignments must be typed using a word processor (Word, WordPerfect) and have a professional look. Use of ACCESS is REQUIRED for this assignment.

In this exercise you play the role of a regional DB Administrator in charge of your assigned territory (see p. 3). You are asked to type original transactional data and prepare them for a DW Load, to be performed in exercise #8.

• Part 7.1: Generate data for each of the following tables:– Load Original Premier Product data into your Original Transactional Database. For

your assigned territory: Create GOOD data for the following tables with at least as many new records as indicated: Rep (2 records); Customer (20 records); Part (10 records); Orders (60; 30 in 2006, 30 in 2007); OrderLine (120, at least one line for every order)

– Make sure that data types agree with case requirements. Dates must fall between 1/1/2013 and 12/31/2013. Change any dates in the case to conform to this standard (for example, if a date currently is 2010, change it to 2013.

– Turn in a printout of each table with data (d3). Note: Include the 5 tables listed above, not the fact table.

Exercise #7 [TEAM PROJECT] p. 2 of 3

• Part 7.2: Revise your Design for the Premiere Products Data Warehouse using a Star diagram (more than one Star OK but not necessary). Include a meaningful Time dimension table.

– Create a NEW Access database .mdb file [PPex7TeamX.mdb], where X is your team #.

– Make sure all field types in the Dimension Tables and in the OrderDetail Fact Table agree with original case specifications, modified to accommodate new data field type. This is critical.

– Use the TIME table that is posted on the course Website (TimeTable2013).

– Turn in ACCESS ERD (deliverable 4) of revised Star Diagram– Turn in Relation Listing (d5). On separate page, clearly identify: All

relations, i.e., Fact tables, dimension tables, primary keys, foreign keys, alternate keys, etc. Use relational notation from Pratt & Adamski. E.g.:

• CUSTOMER[CustomerNum, CustomerName, …, RepNum]– Turn in .mdb file (d6) (CD, email attachment, bring flash disk to

the instructor, etc.)
