Unified Modeling

SAP HANA Developer Guide http://help.sap.com/hana/hana_dev_en.pdf

http://help.sap.com/hana/hana_dev_en.pdf


Unified Modeling - New Model Editor

New integrated view designer for

Attribute and Analytical Views

Simplification of the view authoring

process with just one (technical) view

Apply most-all semantic modeling in

the same output node

Overview

Output Semantics

Node Detail Node columns

Improved efficiency for

SAP HANA modeling

Temporal Joins


Temporal Joins

• The join condition between fact data and attribute data is extended with a time-

dependency

• In the Logical Join, you can create a temporal join between the date field of the

fact table to an interval (to and from) field of the attribute view. The temporal join has to start from the fact table such that the single column must

be in the fact table and, the to and from columns must be in the table that is directly

joined to the fact table.

The join type must be a referential join. The supported data types are timestamp,

date, and integer.

Input Parameters


Input Parameters

Table Input Parameters • Values are automatically derived from a Table instead of user input

View A View B

Discount Table

Prompts User to

enter Discount Rate

when this view is

executed

independently

View B Derives Discount from a Table,

passing discount automatically into View A

without prompting the user

Count


Count - Analytical View

New Count Aggregation type in Analytical Views • Enables counters to be push down


Count - Aggregation Node

Aggregate type on count • Add count measure as an aggregated Column

• Support for sum, min, max aggregation types


Keep Flag & Constant Column

Keep Flag will force columns to be retrieved from the

database even when not requested

Aggregation Node

SELECT DIM_A, DIM_B, GROUP_CONSTANT FROM VIEW

WHERE

(GROUP_CONSTANT = A AND DIM_A IN 2,3,4,5)

OR

(GROUP_CONSTANT = B AND DIM_A IN 6,7,8,9)

Constant Column

Multi Dimensional Reporting


Multi Dimensional Reporting

Analytical View

SELECT ORDER_ID,

SALES_ORG,

MATERIAL

FROM <ANALYTICAL VIEW>

GROUP BY

ORDER_ID,

SALES_ORG,

MATERIAL

Calculation View

• Output node deployed as a projection • Disable if no measures exist

• Aggregation & measures optional

SELECT ORDER_ID,

SALES_ORG,

MATERIAL

FROM <CALCULATION VIEW>

Analytical Privileges

http://help.sap.com/hana/hana_admin_en.pdf




Intermediate results-set Preview

Previewing intermediate result set data

• Data Preview supported for nodes within a Calculation View

• This provides intermediate level data previews in addition to the data preview on

the full model itself


Visualize Plan & Timeline

SQL Editor > Context Menu Administration > Performance > SQL Plan Cache Time Line View

Visualize Plan

Decision Tables


IF the borrower needs a

loan for $14000 for a period

of 36 months and he/she

resides within the same

state then he/she would be

eligible for a 10.25 interest

rate

Interest-rate Calculation

Conditions Actions .. are compact representation

of IF-THEN-ELSE rules

Decision Table Example

Import/Export Rules


Decision Tables Modeling

Ability to model decision tables in SAP HANA Studio • Business Rules vocabulary can be extracted from models based on Calculation Views,

Analytical Views, Physical Tables and Table Types

• Model rules get stored in a compact decision table and provide the ability to simulate and

modify physical data based on actions (e.g. discount %)

Decision Tables - Based on a Table <type>

Sample Input Data Set

LOANREQUESTS

SELECT *

FROM TABLE_TYPE_DT/RV

(PLACEHOLDER = ($$IN_TT$$, LOANREQUESTS))

CALL TABLE_TYPE_DT (LOANREQUESTS,?)

• Decisions based on table types require a input table when executed

• Parameters will enable the creation of a result view (RV)


Decision Tables - Based on a (Table or Modeled View)

Table

INTERESTRATES

CALL TABLE_RAW_DT (?)

SELECT * FROM TABLE_RAW_DT/RV

• Parameters will enable the creation of a result view (RV)

• Results are dynamically calculated, without updating the table


Decision Tables - Based on a Table <Materialized results>

Initial Table

ZINTERESTRATES

• Absence of Parameters will materialize the result

• CALL TABLE_UPDATE_DT (?) will re-execute the rules and

update the table results

SELECT *

FROM ZINTERESTRATES

Extract meaningful information from text

Less data duplication and movement – leverage one infrastructure for analytical

and search workloads

Easy-to-use modeling tools – use HANA Studio Modeler to create search models

Fuzzy search

SELECT CAMP_NO, DEFECT FROM MODELED VIEW WHERE CONTAINS(DEFECT, 'thrtle', FUZZY(0.7));

Relevance ranking

SELECT SCORE() AS S, CAMP_NO, DEFECT FROM TABLE

WHERE CONTAINS(DEFECT, 'throttle engine‘, FUZZY(0.7)) ORDER BY S DESC;

Text Search - SQL search examples


Text Search - Search Models

WHERE CONTAINS(DEFECT, 'throttle engine') ORDER BY S DESC;


Text Search - Definition of Search Rules

Editor is part of the SAP HANA Development perspective

No need to write complex SQL, code can be shared

Rules can be changed without changing the SQL code

Search rules are called using the

EXECUTE_SEARCH_RULE_SET function


Full Text Search

Full text search features has been enhanced to support binary formats

This allows you to search text in .pdf documents or Microsoft Office file formats

SELECT SCORE(), ID, FILENAME, SNIPPETS(PDF_BLOB), HIGHLIGHTED(PDF_BLOB) FROM

DOCUMENTREPO WHERE CONTAINS(PDF_BLOB, 'temporal')

CREATE FULLTEXT INDEX PDF_BLOB_IDX ON DOCUMENTREPO("PDF_BLOB") TEXT ANALYSIS ON
