Structured Query Language (SQL) is a domain-specific language designed for data management for RDBMS. SQL comes particularly handy in managing structured data and offers certain advantages, such as allowing the access of multiple records through a single command and eliminating the need to specify how to access a record. In simpler words, SQL provides tools to the programmer to define, control and manipulate data in a relational model including tables, rows, and columns.

Why learn SQL?
SQL query is purely a text message application which can help you access data. SQL is used for most relational storage systems, and it is more of a query language than a programming language. Learning SQL helps the programmers in accessing data with greater efficiency through basic queries. It is predominantly effectual for data manipulation, and the data stored in SQL is dynamic, which means it can be manipulated and modified at any point of time using a set of basic queries. These features make SQL fully equipped to manage datasets of all shapes and sizes.
