which two statements are true?

When creating Aggregate tables in the OBI repository by using the Aggregate Persistence Wizard,
which two statements are true?

A.
The analyst must first write DML (Data Manipulation Language) scripts to create the aggregate
table.

B.
The Aggregate Persistence Wizard enables you to automate the creation of physical aggregate
tables and their corresponding objects in the repository.

C.
Job Manager can be used to run the Aggregate Persistence script.

D.
The Extraction Transformation and Loading process creates the aggregate tables.

Explanation:
B: The Aggregate Persistence Wizard automates the creation and initial population
of aggregates, persists them in a back-end database and configures the BI Server metadata layer
so that theyre used when appropriate.
C: The wizard then shows me a preview of the script its going to generate, and asks me if I want
to create any more summaries. Heres how the preview script looks note that its not SQL, its a
script language that the BI Server understands and uses as the specification for an aggregation
job, which it then turns into separate CREATE TABLE, INSERT SELECT and so on SQL
statements, optimized for the particular back-end database platform.
Script example:

“ag_Items”
for “Seminar – Complete”.”Items”(“Quantity”)
at levels (“Seminar – Complete”.”Customerdim”.”State”, “Seminar -Complete”.”Productdim”.”Category”, “Seminar – Complete”.”Timedim”.”Year”)
using connection pool “custdw”.”CUSTDW_Pool”
in “custdw”..”CUSTDW”;
