What is SQL?
SQL stands for Structured Query Language. It was initially introduced to the world as SEQUEL (Structured English Query Language). Later, its name changed to SQL, but we still pronounce it as SEQUEL. SQL is basically used to communicate with database. There are bunch of SQL statements which can help you in inserting, updating, retrieving, and deleting data in the database. It is a standard language for RDBMS (Relational Database Management System).
RDBMS is a collection of different kind of services like database engine, SQL server agent, SQL server browser etc which help you in storing and retrieving data from database. To test our SQL statements, we are going to make use of SSMS (SQL Server Management Studio). You can get an evaluation of the software from Microsoft’s website. This tool will help you in communicating with the SQL database using SQL commands.
