How can user-defined functions contribute to improving performance in DB2 applications?
- By minimizing I/O operations
- By optimizing for reusability
- By reducing redundant code
- By simplifying error handling
User-defined functions can contribute to improving performance in DB2 applications by optimizing for reusability. When functions are designed to be reused across multiple queries and applications, it reduces the need for redundant code, leading to improved code maintenance and enhanced application performance. Additionally, by encapsulating frequently used logic within functions, developers can streamline query execution and promote code modularity.
