What is SQL?

SQL, or Structured Query Language, is a powerful and standardised programming language used for managing, manipulating, and retrieving data from relational database systems. Developed in the early 1970s, SQL serves as a bridge between users and databases, enabling efficient communication with databases by executing queries and commands.

SQL operates on relational databases, which store data in structured tables with rows and columns. Users can interact with these databases through the Basic Structure of SQL Queries to perform various tasks, such as creating, modifying, and deleting tables, as well as inserting, updating, and querying data.

SQL Commands include:

a) SELECT (used to retrieve data)

b) INSERT (for adding new data)

c) UPDATE (for modifying existing data)

d) DELETE (for removing data)

SQL also provides capabilities for defining and managing database structures, like indexes, constraints, and views.
