The full form of RDBMS is Relational Database Management System. It is a type of database management system (DBMS) that is based on the relational model of data. In a relational database, data is organized into tables (also known as relations) and is easily accessible using Structured Query Language (SQL) . RDBMSs are widely used to store and manage data in a variety of applications, including online transaction processing, data warehousing, and business intelligence. They are highly scalable and provide many features for data integrity, security, and concurrency control. Some examples of RDBMSs include Oracle, MySQL, and Microsoft SQL Server.
