The SQL Language:
1) SQL is a tool for organizing, managing, and retrieving data stored by a computer database. The name "SQL" is the short form for Structured Query Language.
2) SQL is a computer language that you use to interact with a database. In fact, SQL works with one specific type of database, called a relational database.
3) The computer program that controls the database is called a database management system, or DBMS. Like MSSQL Server, MySql etc.
4) When you need to retrieve data from a database, you use the SQL language to make the request. The DBMS processes the SQL request, retrieves the requested data, and returns it to you. This process of requesting data from a database and receiving back the results is called a database query—hence the name Structured Query Language.
