Scenario: A company wants to enforce business rules consistently across various database applications in DB2. How can user-defined functions facilitate this requirement?
- User-defined functions can be invoked directly by end-users, bypassing the enforcement of business rules.
- User-defined functions can execute only read-only operations, restricting their usefulness in enforcing business rules.
- User-defined functions can implement complex business logic, ensuring consistent enforcement of rules across applications.
- User-defined functions can only be invoked from stored procedures, limiting their applicability to enforcing business rules.
User-defined functions play a crucial role in enforcing business rules consistently across various database applications in DB2. By encapsulating complex business logic, UDFs ensure that the same rules are applied uniformly across different components of the system. This promotes data integrity, reduces errors, and enhances compliance with business requirements, thereby facilitating seamless operations across applications.
