A DBMS is a system software used for creating and managing databases. It allows users to access database, and manipulation of the data. MySQL is one of the popular DBMS software.

Types of DBMS- There are four major types of DBMS

  • Hierarchical DBMS- In this type of DBMS, data is represented using a “parent-child” relationship. This type is rarely used nowadays. Example- Windows registry used in Windows XP.
  • Network DBMS- This type of DBMS supports a “many-to-many” relationship. It results in complex database structures. Example- RDM Server
  • Relational DBMS- In this type, data is stored in the form of tables, also known as “relations”. This is the most popular type of DBMS used in the market. Example- MySQL, Oracle, etc.
  • Object oriented RDBMS- As the name suggests, the data is stored in the form of objects. The objects have attributes and methods that define what to do with the data. Example- PostgreSQL.

What is Structured Query Language (SQL)? – SQL is the crux of a relational database. It is primarily used for managing and accessing the database. With the help of SQL, you can add, update or delete the rows of the data, modify the databases, and many more actions. We can say that SQL is the language which is responsible for operating the database.

SQL commands- These commands are divided into four groups

  • DDL (Data Definition Language)- As the name indicates, DDL consists of a set of commands used to define the database. It is used to create and modify the structure of the database objects. Example of DDL commands-
  • CREATE-create a database
  • DROP-delete from database
  • ALTER-alter the database
  • TRUNCATE-delete all records from a table
  • COMMENT-add comments to the data dictionary
  • RENAME-rename an object in the database

DML (Data Manipulation Language)-

It includes the set of commands used to manipulate the data present in the database. Examples of DML commands-

  • SELECT-retrieve data from the database
  • INSERT-insert data into the table
  • UPDATE-update existing data within the table
  • DELETE-delete records from the table

DCL (Data Control Language)-

It includes the commands which primarily deals with the controls of the database. Example of DCL commands-

  • GRANT-allows user’s access privileges to the database
  • REVOKE-withdraw user access privileges given by GRANT

TCL (Transaction Control Language)-

It mainly deals with the transactions carries out in the database. Examples of TCL commands are-

  • COMMIT-commits a transaction
  • ROLLBACK-rollback a transaction if any error occurs
  • SAVEPOINT-sets a save point within the transaction
  • SET TRANSACTION-specify the characteristics of the transaction
