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.
