How can user-defined functions enhance code readability and maintainability in DB2?
- All of the above
- By encapsulating complex logic
- By promoting modular development
- By reducing the need for repetitive code
User-defined functions can enhance code readability and maintainability in DB2 by encapsulating complex logic, reducing the need for repetitive code, and promoting modular development. Encapsulating logic within functions improves code readability by abstracting implementation details and providing a clear interface for other developers to use. Additionally, modular development facilitates code reuse and simplifies maintenance efforts by isolating changes to specific functions rather than scattering them throughout the application.
