The RDBMS provides an interface between users and applications and the database, as well as administrative functions for managing data storage, access, and performance.

Why was DBMS introduced?

To develop software applications In less time. Data independence and efficient use of data. For uniform data administration. For data integrity and security.

When was RDBMS created?

The relational database was first defined in June 1970 by Edgar Codd, of IBM’s San Jose Research Laboratory. Codd’s view of what qualifies as an RDBMS is summarized in Codd’s 12 rules.

  • Storage: With DBMS, data is stored as a file, while RDBMS stores data in the form of tables.
  • Users: While RDBMS can accommodate multiple users, DBMS allows only one user.
  • ACID:
  • Type of Program:
  • Hardware and Software Needs:
  • Normalization:
  • Distributed Databases:
  • Data Quantity:
