PL/SQL (Procedural Language for SQL) is Oracle's proprietary extension to standard SQL. It combines the data manipulation power of SQL with the procedural capabilities of a programming language. PL/SQL allows developers to write complex database-centric applications by incorporating variables, conditions, loops, error handling, and modular programming constructs like procedures and functions. This language is tightly integrated with Oracle databases, enabling efficient data processing and transaction management.
