What is SQL?

SQL, or Structured Query Language, is a standard language for managing and manipulating data held in relational database management systems (RDBMS). It allows users to define, access, and control data, enabling operations like creating databases, inserting, updating, deleting, and retrieving data based on specific criteria. SQL provides a structured way to interact with databases, ensuring data integrity and consistency.
