RDBMS stands for Relational Database Management System. It is a type of database management system that stores and manages data in a relational format, meaning that it organizes data into tables consisting of rows and columns, with each row representing a record and each column representing a specific attribute of the record.
RDBMS software provides a set of tools for creating, modifying, and querying relational databases. It ensures the consistency, accuracy, and integrity of the data stored in the database, and it supports a variety of operations such as adding, modifying, deleting, and retrieving data.
The relational model used by RDBMS is based on the concept of a primary key, which is a unique identifier for each record in a table. It also allows for the establishment of relationships between tables, which makes it possible to link data from multiple tables in a single query.
Some popular examples of RDBMS include Oracle, Microsoft SQL Server, MySQL, PostgreSQL, and SQLite. RDBMS are widely used in a variety of applications, ranging from simple data storage systems to complex business applications and data warehousing.
