Database management System

  • Duaration - 3 Months

A DBMS is a software that allows creation, definition and manipulation of database, allowing users to store, process and analyse data easily. DBMS provides us with an interface or a tool, to perform various operations like creating database, storing data in it, updating data, creating tables in the database and a lot more. DBMS also provides protection and security to the databases. It also maintains data consistency in case of multiple users.
