You need to modify the schema

You are modifying a star schema data mart that feeds order data from a SQL Azure database into a SQL
Server Analysis Services (SSAS) cube. The data martcontains two large tables that include flags and
indicators for some orders. There are 100 differentflag columns, each with 10 different indicator values. Some
flags reuse indicators. The tables both have a granularity that matches the fact table.
You have the following requirements:
Allow users to slice data by all flags and indicators.
Modify the date dimension table to include a surrogate key of a numeric data type and add the surrogate key to
the fact table.
Use the most efficient design strategy for cube processing and queries.
You need to modify the schema.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

A.
Define the surrogate key as an INT data type. Combine the distinct flag/indicator combinations into a single
dimension.

B.
Define the surrogate key as an INT data type. Create a single fact dimension in each table for its flags and
indicators.

C.
Define the surrogate key as a BIGINT data type. Combine the distinct flag/indicator combinations into a
single dimension.

D.
Define the surrogate key as a BIGINT data type. Create a single fact dimension in each table for itsflags
and indicators.
