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.
