Questions 14

You are defining a data store in ODI metadata and want to add a primary key even if it does not physically exist on the related database catalog.

How can you accomplish this? (Choose the best answer.)

Options:

A.

You can add a primary key even if it does not physically exist on the related database catalog, by adding constraintson the data store.

B.

You can add a primary key even if it does not physically exist on the related database catalog, by adding constraints to the data store diagram.

C.

You cannot add a primary key if it does not physically exist on the related database catalog. You can flag only non-null conditions to be checked.

D.

You cannot add a primary key if it does not physically exist on therelated database catalog. You can reverse engineer only the existing constraints.
