Procedures in a database are stored code segments, which can be executed. This is a good way of holding any business logic in a single place. A procedure could be very simple and return the value of the square of two number, or be very complicated, and perform a lot of data validation before inserting data into a table or updating a table for example.
The procedures of a database typically include tasks such as data modeling, database design, implementation, querying, indexing, optimization, security, maintenance, and backup/recovery. These procedures are essential for ensuring data integrity, performance, and availability within a database system.
