Explaining the Difference Between a Package and a Procedure in PL/SQL

The main focus keyword difference between a package and a procedure in PL/SQL is that a procedure is a standalone program unit that performs a specific task, while a package is a collection of related procedures, functions, variables, and other PL/SQL constructs grouped together to provide a modular approach to programming.

Procedures in PL/SQL are similar to functions in other programming languages, as they contain a series of SQL and PL/SQL statements to perform a specific action. They can take input parameters and return values, making them reusable and efficient for performing specific tasks.

On the other hand, packages in PL/SQL serve as containers for procedures, functions, variables, and other program constructs. They provide a way to encapsulate related logic and data, making it easier to manage and maintain code. Packages allow for better organization and reusability of code by grouping related elements together.

In summary, while a procedure is a standalone program unit focused on performing a specific task, a package is a collection of related program constructs aimed at providing a modular and organized approach to programming in PL/SQL.
