A stored procedure is a precompiled collection of SQL statements stored under a name and processed as a unit, which can be executed repeatedly.

Parameters allow stored procedures to accept input values, making them flexible and reusable for different scenarios.

Stored procedures improve performance by reducing network traffic, enhance security by controlling access, and centralize business logic.
