What is an RDBMS?
RDBMS or Relational Database Management system is a database management system (DBMS) designed specifically for administrating relational database tables. An RDBMS stores transactional data in two-dimensional tables: each row in a table contains a single record; ongoing events continue to record/add to the appropriate tables that relate to the record for every occurrence of a transaction. An RDBMS operating system allows user to create, retrieve, modify, update and administer a relational database.
