What considerations should be taken into account when designing efficient user-defined functions in DB2?
- Minimize I/O operations
- Optimize for reusability
- Proper error handling
- Use of deterministic functions
When designing user-defined functions in DB2, it's crucial to consider optimizing for reusability. This involves writing functions that can be utilized across multiple queries and applications, reducing the need for redundant code. By focusing on reusability, developers can enhance code maintenance and improve overall application performance.
