Final answer:
Triggers and stored procedures can greatly enhance database design and performance. Triggers enforce business rules and maintain data integrity, while stored procedures reduce network traffic and improve execution times. Together they contribute to a more robust and efficient database system.
Step-by-step explanation:
Triggers and stored procedures are powerful SQL features that can enhance database design and performance. Triggers are special types of stored procedures that automatically execute or 'fire' when certain events occur in the database, such as INSERT, UPDATE, or DELETE actions. They can be used to enforce complex business rules at the database level, maintain data integrity, and update other tables which can eliminate the need for some external application logic and reduce the number of round-trips between an application and the database.
Stored procedures are predefined SQL codes that can be saved and reused repeatedly. They offer several performance benefits by reducing network traffic, improving execution times through SQL statement reuse, and simplifying complex operations into single calls. Additionally, because stored procedures are compiled and optimized by the database server, they can lead to more efficient execution plans hence improving the overall performance. The use of both tools can lead to a more robust, secure, and efficient database system.
