Have you used stored procedures or functions inside a database in your project?

Yes, stored procedures and functions are often used within databases in projects to perform repetitive or complex operations on the DBMS side. This allows:

• Reducing the load on the application by executing logic directly in the database.
• Improving performance through query optimization.
• Providing centralized management of business logic, which simplifies maintenance.

For example, a stored procedure was used in the project to calculate the final cost of an order considering discounts and taxes, called from Java code via JDBC.
