Answer: B
The use of structured query language (SQL) facilitates
portability. Verification of import and export procedures
with other systems ensures better interfacing with other
systems, analyzing stored procedures/triggers ensures proper
access/performance, and reviewing the design,
entity-relation model will all be helpful but do not
contribute to the portability of an application connecting
to a database.
