Explain a few advantages of a DBMS.

Answer»

Following are the few advantages of using a DBMS. 

  • Data Sharing: Data from a single database can be simultaneously shared by multiple USERS. Such sharing also enables end-users to REACT to changes quickly in the database environment.
  • Integrity constraints: The existence of such constraints allows storing of data in an organized and refined manner.
  • Controlling redundancy in a database: Eliminates redundancy in a database by providing a mechanism that integrates all the data in a single database.
  • Data Independence: This allows changing the data structure without altering the composition of any of the executing application programs.
  • PROVIDES backup and recovery facility: It can be configured to automatically create the backup of the data and restore the data in the database whenever required.
  • Data Security: DBMS provides the necessary tools to make the storage and transfer of data more reliable and secure. Authentication (the process of GIVING restricted ACCESS to a user) and encryption (encrypting sensitive data such as OTP, credit card information, etc.) are some popular tools used to secure data in a DBMS.
