NEW QUESTION # 39
If you have a database with four aggregate tables, how should the repository be configured to take advantage of the aggregates?

A. By creating four new logical table sources and using the "where" section of the Content tab to specify the aggregation levels
B. By creating four new logical table sources and choosing each dimension's level of aggregation in the Content tab
C. By creating four new logical tables sources
D. By creating four new logical table sources and using the Fragmentation content to specify the aggregation levels

Answer: B

Explanation:
Explanation/Reference:
Content Tab
Aggregation Content
You can define the aggregation (ie the group by) of:
by hierarchy level
by logical column
It helps you to define an aggregate navigation

Note: logical table source
Logical table sources define the mappings from a single logical table to one or more physical tables. A logicaltable contains one or more logical table source. The mapping between physical columns and logical columns are done in this element.
The definition of the logical table source is used:
to specify transformations/calculations (in the column mapping tab),
to enable aggregate navigation and fragmentation (in the content tab)
The Content tab of the Logical Table Source is used to define :
any aggregate table content definitions (specify the grain of the physical tables), fragmented table definitions for the source, and WHERE clauses (if you want to limit the number of rows returned).

NEW QUESTION # 40
Which are the three types of tables available to physical tables in the physical layer?

A. View
B. Table
C. Select
D. Stored Proc
E. Physical Table

Answer: C,D,E

Explanation:
Explanation
Pull the table and column definition into the physical layer
Use the OBIEE "import metadata" wizard to pull the table and column definition into the physical layer. The wizard is used so that all of the column definitions do not need to be manually added into the physical layer.
Figure:

Note: The physical layer is the layer of the Logical Business Model where you define the physical data model of your data source. It contains information about the physical data sources.
