Benefits of Views:

Views can represent a subset of the data contained in a table

Views can join and simplify multiple tables into a single virtual table

Views can act as aggregated tables, where the database engine aggregates data (sum, average etc)and presents the calculated results as part of the data

Views can hide the complexity of data; for example a view could appear as Sales2000 or Sales2001,transparently partitioning the actual underlying table

Views take very little space to store; the database contains only the definition of a view, not a copy ofall the data it presents

Depending on the SQL engine used, views can provide extra security

Views can limit the degree of exposure of a table or tables to the outer world


5/23


Advanced View Features:

Various databases have extended the basic views from simpleread-only to updatable data sets frequently used in DataWarehousing:

ORACLE introduced the concept of MATERIALIZED VIEW which not

only expose the data but allow for its modification

IBM DB2 has MQTs (Materialized Query Tables).

Similarly MSSQL has Indexed Views


6/23


Behind the Scenes:

View Query (VIEW_1):

SELECT OBJECT_ID, OBJECT_NAME FROM SOME_TABLE

Usage:

SELECT * FROM VIEW_1

Behind the scenes the Database does this:

SELECT * FROM (SELECT OBJECT_ID, OBJECT_NAME FROM SOME_TABLE) VIEW_1


7/23


Derived Tables in BO Universe are SELECT statements thatallow for the exact same functionality as using a Database View

Benefits: Easy to maintain

Same Database performance as using a View

Quicker and faster to develop (Views require database permissions to create and use)


8/23


Reasons to use a View over a Derived Table:

Views can be re-used in multiple universes and maintained within theDatabase

Views may offer additional performance if they are Materialized/Indexed

Views (depending on the platform) Views can be integrated with Database security to limit access to data


9/23

Using DTs to Group Data

In the following example we have a sample universe withtransaction level data:


10/23


Our goal is to create statistical analysis reports that grouptransactions into buckets (size and unit of measure defined atrun-time as well as number of buckets to show).

Buckets are containers for transactions, e.g. a Bucket containing5 entries, means that there are 5 transactions within the bucketsize (e.g. 0-30 days).

Hands-on Example


12/23

Universe Security

Access Restrictions in Universe Designer allow for restrictions tobe put in place on an individual user or group basis.

The following items can be managed:

Connection Controls (number of records)

SQL generation (allow the use of sub queries, etc.)

Objects (disable use of objects defined in the list)

Rows (automatically append a WHERE clause to specific tables

Table Mappings (automatically map to another table/view that has the same

structure)


13/23

Universe Security

Sample access restriction shown below:

Universe Security

Pass-through authentication can also be used in one of twoways:

Enterprise

AD/KERBEROS Delegation


15/23

Universe Security

Enterprise authentication to DB pass-through uses DB_USERand DB_PASS properties as defined in the CMC:

It will utilize DB named user accounts as defined in thedatabase and is configured on an individual basis.


16/23

Universe Security

AD/KERBEROS authentication can also be passed through ifusing SSO using delegation.

Presently this is only supported on the Microsoft Platform(Windows) with SQL Server database.

Benefits include the ability to use AD groups to manage securitywithin the database (access to tables/views/columns)


17/23

Universe Security

Pass-through configured in Designer Connection Parameters:

This requires KERBEROS to be configured for SSOauthentication


18/23

Aggregate Awareness

Business Objects Universe supports the notion of AggregateAwareness which can dynamically select an aggregate table(summary) to improve query performance depending on thelevel of granularity of objects selected in the query.


19/23

Aggregate Awareness

We can use the Transaction Amount Measure and define it to beAggregate Aware using the @ function.


20/23

Aggregate Awareness

Afterwards we need to define incompatibilities to trigger thedetail level of aggregate awareness (otherwise only thesummary is used)


21/23

Aggregate Awareness Now when I generate a report using only the Transaction Amount I get the

following SQL:

But when I add any other dimension the SQL automatically changes to use thedetail table for the measure:
