The purpose of PL/SQL is to combine database language and procedural programming language. This PL/SQL was developed by Oracle Corporation in the early to enhance the capabilities of SQL. It permits you to store compiled code directly into the database. PL/SQL also enables you to define triggers, which are subprograms that the database executes automatically in response to specified events.
