what is a relational database management system

A Relational Database Management System (RDBMS) is a type of database management system (DBMS) that organizes data into one or more tables, with each table consisting of a set of rows and columns. The data is stored in a way that allows for efficient and flexible querying and manipulation.

In a relational database, the relationships between data elements are defined by the tables and their respective columns, which serve as keys to link the data. This allows for the creation of complex queries that can span multiple tables and return the desired data in a structured and organized format.
