    What is DBMS?

    A database-management system (DBMS) is a group of interrelated facts and a set of applications to create those data. This is a group of associated data with an implicit meaning and hence is a database. The group of data, commonly called as the database includes records relevant to an enterprise. The main objective of a DBMS is to support a method to save and retrieve database records that is both convenient and efficient.

    What is RDBMS?

    RDBMS stands for Relational Database Management System. RDBMS information is structured in database tables, fields, and records. Each RDBMS table includes database table rows. Each database table row contains one or more database table fields. RDBMS saves the document into a group of tables, which may be associated with general fields (database table columns).

    The most famous RDBMS is MS SQL Server, DB2, Oracle, and MySQL.
