In this RDBMS vs DBMS tutorial, we will learn about main RDBMS and DBMS difference. But before that, let’s learn:
What is DBMS?
A DBMS is a software used to store and manage data. The DBMS was introduced during 1960’s to store any data. It also offers manipulation of the data like insertion, deletion, and updating of the data.
DBMS system also performs the functions like defining, creating, revising and controlling the database. It is specially designed to create and maintain data and enable the individual business application to extract the desired data.
What is RDBMS?
Relational Database Management System (RDBMS) is an advanced version of a DBMS system. It came into existence during 1970’s. RDBMS system also allows the organization to access data more efficiently then DBMS.
RDBMS is a software system which is used to store only data which need to be stored in the form of tables. In this kind of system, data is managed and stored in rows and columns which is known as tuples and attributes. RDBMS is a powerful data management system and is widely used across the world.
KEY DIFFERENCE
DBMS stores data as a file whereas in RDBMS, data is stored in the form of tables.
DBMS supports single users, while RDBMS supports multiple users.
DBMS does not support client-server architecture but RDBMS supports client-server architecture.
DBMS has low software and hardware requirements whereas RDBMS has higher hardware and software requirements.
In DBMS, data redundancy is common while in RDBMS, keys and indexes do not allow data redundancy.
