The full form of RDBMS is ” Relational Database Management System .” An RDBMS is a type of DBMS designed specifically for relational databases. Therefore RDBMSes are actually subset of DBMSes.
A relational database is actually a database that stores data in a structured format, using rows and columns. This makes it easy to locate and access certain specific values in the database. It is called ” relational ” because it has values related to each table with each other. Tables are also related to each other. This relational structure makes it possible that queries can be run across multiple tables at the same time.
While a relational database describes the type of database that an RDMBS manages, RDBMS refers to the database program itself. This is a software that executes queries above the data, which includes adding, updating, and searching for values.
An RDBMS also provides a visual representation of the data. For example, it displays data in a table such as a spreadsheet, which allows you to view them and even edit individual values in that table. Some RDMBS programs allow you to create forms that allow streamline entering, editing, and deleting of data.
Most of the well-known DBMS applications fall under this RDBMS category. For example, Oracle Database, MySQL, Microsoft SQL Server, and IBM DB2. Some programs support non-relational databases, but they are primarily used for relational database management.
