SQL (Structured Query Language) is a standardized programming language for managing and manipulating relational databases. In a relational database, data is organized into tables with rows and columns, making it easy to understand and manipulate.
SQL is the primary language used to interact with all relational databases (such as MySQL, MS Access, Oracle, Sybase, Informix, PostgreSQL and SQL Server). It allows users to perform various operations, such as querying data, updating records, and managing database structures.
SQL is relatively easy to learn as it uses common English words in its commands.
