Why are testing and evaluation of the database and applications not done by the same people who are responsible for design and implementation? What minimum standards must be met during testing and evaluation?

Program Plan Intro

Database Administrator (DBA's):

The person responsible for the maintaining the shared and centralized database is known as Database Administrator (DBA).

The role and responsibilities of the DBA varies from organization to organization based on the size of the organization. Based on the organization, DBA defined either in line position or staff position.

The DBA’s technical role needs the functions of database management system (DBMS), structure, programming languages, and methodologies of data-modeling and design.

Explanation of Solution

Reasons that the same people not testing and evaluating the database and application:

Testing and evaluation services are closely associated to design and implementation of database service. But, they typically maintained independently.

  • The reason for separating the people from “testing and evaluation” and “design and implementation” process is that application programmers and designers are frequently too near to issue that studied to identify the faults and omissions.
  • Testing begins with filling the test bed database which includes the test data for applications.
  • Its purpose is to verify the “data definition” and “database integrity rules” and “application programs”...
