PL/SQL Packages

PL/SQL packages are collections of related code components—such as procedures, functions, variables, and other programs—bundled together into a single unit. Think of them as a toolbox that organizes tools for specific tasks, making it easier to develop, maintain, and reuse code efficiently in a database environment. Packages help improve performance by reducing the number of times database objects are accessed and provide a modular structure, enabling developers to manage complex applications systematically. Essentially, they streamline database programming by grouping related functionalities for better organization and efficiency.
