The full form of DBMS is Database Management System. It is a software used for storing, retrieving, and managing data in a database. DBMSs incorporate the relational-data model and are normally accessed using a Structured Query Language (SQL) application programming interface. The software is used to create, read, update, and delete data in a database, and it ensures that data is consistently organized and remains easily accessible. The software is also used to manage the security of the data stored in the database.
