What is SQL used for?

• A. Formatting spreadsheets
• B. Creating executable programs
• C. Querying, updating, and managing data in relational databases
• D. Rendering graphics

Answer: (C)

SQL is the language for working with relational databases, allowing you to specify what data you want and how to change it without writing step-by-step procedures. It lets you query data with SELECT, add new rows with INSERT, modify existing values with UPDATE, and remove rows with DELETE. It also handles creating and altering the database structure and managing permissions (things like CREATE, ALTER, DROP). Because SQL focuses on describing data operations rather than rendering or formatting, it’s the go-to tool for querying, updating, and managing data in relational databases. Formatting spreadsheets, creating executable programs, and rendering graphics are tasks handled by other kinds of software.
