expect the job description of the DBA to include:
A. defining the conceptual schema.
B. defining security and integrity checks.
C. liaising with users in developing data model.
D. mapping data model with the internal schema.
Answer / guest
Answer: D
A DBA only in rare instances should be mapping data elements
from the data model to the internal schema (physical data
storage definitions). To do so would eliminate data
independence for application systems. Mapping of the data
model occurs with the conceptual schema since the conceptual
schema represents the enterprisewide view of data within an
organization and is the basis for deriving an end-user
department data model.
