Which of the following would help to ensure the portability of an application connected to a database?

A.
Verification of database import and export procedures

B.
Usage of a structured query language (SQL)

C.
Analysis of stored procedures/triggers

D.
Synchronization of the entity-relation model with the database physical schema

Explanation:
The use of 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 be helpful, but none of these contribute to the portability of an
application connecting to a database.
