What is PL/SQL?

PL/SQL (Procedural Language/SQL) is Oracle's procedural extension to SQL. It allows you to write stored procedures, functions, and triggers to automate database tasks and enhance application logic.

Benefits of Learning PL/SQL:

• Improved Performance: Execute complex operations within the database for faster processing.
• Enhanced Security: Control data access and enforce business rules.
• Code Reusability: Create reusable components for efficient development.
• Data Integrity: Maintain data consistency through stored procedures and triggers.
