3. What is Structured Query Language (SQL)?SQL is a special language that helps computers find, add, change, and delete information in big tables called databases. It lets people ask questions about data without having to write complicated code.
4. Why do computers use SQL instead of other ways to find data?SQL lets users say what data they want, and the computer figures out the fastest way to get it. This makes working with data easier and faster for everyone.

Relational Database Management System (RDBMS): Software that manages data in a relational model, allowing for structured querying and manipulation.
Declarative Programming: A programming paradigm that expresses the logic of a computation without describing its control flow.
Query Optimization: The process by which a database management system determines the most efficient way to execute a given SQL query.
