Guidelines

The following sections describe some areas for you to consider as you prepare your database and your COBOL program.

Guideline 1 - Database Administrator
A site with a database management system needs a database administrator (DBA).
Guideline 2 - Understand COBOL Operations and Database Operations
Some COBOL operations are particularly stressful to a database. The more the application uses these operations, the more likely performance of the RDBMS suffers.
Guideline 3 - Program and Database Interaction
A database can interact with your COBOL program in surprising ways. When you introduce a database to a mature COBOL application, your application may experience errors you have not seen before. Being aware of this possibility helps you to prepare your response.
Guideline 4 - Plan for Growth
Planning ahead for growth is essential. You need to be able to predict the system resources that your application requires reaching a full load, both in terms of users and database size.
