It is also needed to write a query for storing, manipulating, or retrieving the database data.

Purpose: SQL is needed to write commands for specifying relational database schemas.

On the other hand, SQL Server was developed by Microsoft in the year 1989 for commercial purposes. It is a standard query language, that is standardized by ANSI(American National Standards Institute) in 1986 and ISO(International Organization for Standardization) in 1987.

Developed By: SQL was developed by IBM in around 1970s.

It also provides some additional features and functionalities, so that the user can properly interact with the database and can perform all the database operations efficiently.

On the other hand, SQL Server is proprietary software or an RDBMS tool that executes the SQL statements. It is used to write queries to retrieve or manipulate the relational database data. Also, the SQL Server has frequent security and operational updates that make it more popular. It has both command-line and GUI(Graphical User Interface) for providing better user operations. But SQL Server is easy to use and provides better functionalities and user-friendly operations. There are some other RDBMS also available like Oracle, DB2, etc. The latest version of the SQL Server is 15.0, which is released in the year 2019.

SQL Server is supported by the Microsoft Windows and Linux operating systems. The SQL Server is platform-dependent, different software is available for different platforms. T-SQL is almost the same as SQL with slight variations in the queries. It uses a different form of SQL, which is called T-SQL(Transact Structured Query Language). It is proprietary software developed using C and C++ languages. The SQL Server is developed by Microsoft in the year 1989 for commercial purposes. Moreover, it also manages and performs all the database operations. It is an application that stores the database data and executes the SQL commands and queries to manipulate the relational database. SQL Server, also known as MS SQL Server is an RDBMS(Relational Database Management System). You can learn more about these SQL commands here. Some of the TCL commands are COMMIT, ROLLBACK, SAVEPOINT, etc. TCL(Transaction Control Language): TCL deals with the transactions within the relational database.

Some of the DCL commands are GRANT, REVOKE, etc.

DCL(Data Control Language): DCL is a language used to control access to data stored in the database.

Some of the DML commands are SELECT, INSERT, UPDATE, DELETE, etc.

DML(Data Manipulation Language): DML enables a database user to access or modify the data stored in the database that is organized by appropriate data models.

Some DDL commands are CREATE, DROP, ALTER, TRUNCATE, etc.

DDL(Data Definition Language): DDL is used to specify the relational database schema, which is usually hidden from the database users.

SQL is further divided into four sub-languages, that are as follows: It is to be noted that the queries can only be written using SQL, but we need some RDBMS(Relational Database Management Systems) like SQL Server, Oracle to execute those SQL commands and queries. It is also standardized by ANSI(American National Standards Institute) in 1986 and ISO(International Organization for Standardization) in 1987.

It is a query language that can be used to write queries to create schema, store, manipulate, and retrieve data from the relational database. SQL is the acronym for Structured Query Language. So, let us start learning them one by one. So in this blog, we'll first have a brief introduction about SQL and SQL server, and then we'll differentiate them based on some points. In fact, SQL is a query language that is used to write the database queries, which are executed by some database engines like SQL Server, Oracle, etc. Whenever we perform database operations, we think that SQL itself executes those operations.
