===Stored procedures===
{{Main|Stored procedure}}
A stored procedure is executable code that is associated with, and generally stored in, the database. Stored procedures usually collect and customize common operations, like inserting a [[tuple]] into a [[relation (database)|relation]], gathering statistical information about usage patterns, or encapsulating complex [[business logic]] and calculations. Frequently they are used as an [[application programming interface]] (API) for security or simplicity. Implementations of stored procedures on SQL RDBMS's often allow developers to take advantage of [[Procedural programming|procedural]] extensions (often vendor-specific) to the standard [[Declarative programming|declarative]] SQL syntax.
Stored procedures are not part of the relational database model, but all commercial implementations include them.
