PL SQL stands for Procedural Language/Structured Query Language. It is a programming language designed specifically for the Oracle Database Management System (DBMS).
PL/SQL is a procedural language because it includes constructs such as loops, conditions, and subprograms that enable developers to create complex, multi-step procedures and functions. It is also a structured query language because it allows developers to write SQL statements to retrieve and manipulate data within the Oracle database.
PL/SQL was created by Oracle Corporation in the late 1980s and has since become an integral part of the Oracle database system. It is used for a variety of purposes, such as building custom applications, creating stored procedures and triggers, and managing the database.
PL/SQL programs are typically stored in the database and can be executed on demand by users or other applications. They can be written in a variety of development environments, including Oracle’s SQL Developer, Oracle Forms, and Oracle Application Express.
PL/SQL code is compiled and executed on the server-side, which makes it faster and more efficient than client-side scripting languages. It also provides additional security features, such as fine-grained access control, which allows developers to control who has access to specific database objects and operations.
In summary, PL/SQL is a powerful and flexible programming language that enables developers to create complex applications and manage the Oracle database efficiently and securely.
