RDBMS

RDBMS is abbreviated Relational Database Management System;

In the relational database system, data is kept in tables and these tables can be related to each other in a relational sense. We can explain a relational database as a database consisting of data organized among various tables.

The data between these different tables are linked to each other by means of various keys. Related tables have a key column between the columns. Through this key column, data from multiple tables can be linked and displayed together in any query.

Among such databases:

  • MSSQL,
  • PostgreSQL,
  • MySQL,
  • Oracle,
  • dBase,
  • Informix,
  • Ingres are the leading ones.

Data in RDBMS is stored in database objects called tables. This table is basically a collection of related data entries and consists of many columns and rows.
A table is the most common and simplest form of data storage in a relational database.
