RDBMS stands for Relational Database Management System. It is a type of database management system (DBMS) that stores data in a row-based table structure which connects related data elements. An RDBMS includes functions that maintain the security, accuracy, integrity, and consistency of the data. It provides an interface between users and applications and the database, as well as administrative functions for managing data storage, access, and performance. RDBMS is the most popular database system among organizations across the world. Many relational database systems are equipped with the option of using SQL (Structured Query Language) for querying and updating the database. The most common definition of an RDBMS is a product that presents a view of data as a collection of rows and columns, even if it is not based strictly upon relational theory.
