What are the advantages and disadvantages of using stored procedures in a database?

Advantages of stored procedures:

• Executed on the database server, reducing network load and client application load.
• Improve performance through compilation and optimization of queries within the DBMS.
• Provide centralized logic, simplifying maintenance and updates.
• Enhance security by restricting direct access to tables and allowing only procedure execution.

Disadvantages:

• Dependence on a specific DBMS, reducing application portability.
• Debugging and testing are more complex compared to application-side code.
• Architecture may become more complicated with excessive use.
• Limitations in programming languages and capabilities across different DBMSs.

Thus, stored procedures are useful for optimization and security but require careful use and can complicate maintenance when there is a large volume of logic in the database.
