A Database Management System (DBMS) is a software system used to manage and manipulate data in a database. It serves as an interface between an end-user and a database, allowing users to create, read, update, and delete data in the database. DBMS manage the data, the database engine, and the database schema, allowing for data to be manipulated or extracted by users and other programs. The main tasks of a DBMS include creating and managing databases, protecting data, reading, updating, and deleting data, and defining the database schema. DBMS also provide data security, data integrity, concurrency, and uniform data administration procedures.
DBMS can be classified based on a variety of criteria such as the data model, the database distribution, or user numbers. The most widely used types of DBMS software are commercial DBMS such as MySQL and Oracle. DBMS allows users to perform the following tasks:
- Create and modify databases
- Query databases
- Define database schemas
- Protect data
- Read, update, and delete data
- Manage databases
The first DBMS was developed in the early 1960s when Charles Bachman created a navigational DBMS known as the Integrated Data Store. Shortly after, IBM developed Information Management System (IMS), a hierarchical DBMS designed for IBM mainframes thats still used by many large organizations.
In summary, a DBMS is a software system that allows users to manage and manipulate data in a database. It provides an interface between an end-user and a database, allowing users to create, read, update, and delete data in the database. DBMS manage the data, the database engine, and the database schema, providing data security, data integrity, concurrency, and uniform data administration procedures.
