When you write a COBOL program with SQL and you send it for review, the reviewer might have questions and look for guidelines. Here are the top 5 guidelines to help you review a program written in SQL:
Guidelines to Review SQL Queries
- Follow coding standards: Ensure that the program adheres to established coding standards and conventions. This includes consistent indentation, naming conventions, and commenting practices.
- Verify data integrity: Check if the program correctly handles data operations, such as inserting, updating, and deleting records. Ensure that appropriate error handling is in place to maintain data integrity.
- Optimize performance: Review the program’s efficiency by examining the SQL queries being used. Look for any potential performance bottlenecks, such as improper indexing, unnecessary joins, or inefficient sorting.
- Test against various scenarios: Evaluate the program’s behavior under different scenarios and edge cases. For example, test it with different input values, large datasets, and concurrent user access to identify any potential issues.
- Ensure security measures: Verify that the program follows security best practices, such as using parameterized queries to prevent SQL injection attacks. Check if proper access controls are in place to protect sensitive data.
By following these guidelines, reviewing a program written in SQL will become much easier.
Below is really a checklist for you and best practices to review SQL program. In general these are applied to any high level language like Java, C# etc. and not only COBOL.
