What is the full form of SQL?

The full form of SQL is Structured Query Language. This language is specifically designed for managing and manipulating relational databases. SQL allows users to perform a variety of operations such as retrieving data, updating records, and managing database structures.

The term "structured" reflects the organization of data into tables that can be easily accessed and manipulated according to defined relationships. This structure enables complex queries that can join multiple tables and filter results based on various criteria, making SQL a powerful tool for data analysis and management.

In contrast to the other options, "Standard Query Language" incorrectly suggests that SQL is fundamentally about establishing a standard rather than highlighting its structured nature. "Simple Query Language" inadequately describes the comprehensive capabilities of SQL, and "Systematic Question Language" does not relate accurately to the language's purpose or use. Each of these alternatives misses the essential characteristic of SQL being specifically designed to interact with structured data in databases.
