Being a computer student, it is a very common question that what is the difference between DBMS and RDBMS? It have been asked in most of the examinations.  So in this article, we will discuss the main difference between DBMS and RDBMS.

What is DBMS?

Database Management System (DBMS) is a software that is deployed to define, create, and maintain a database and provides controlled access to the data.

What is RDBMS?

Relational Database Management System (RDBMS) is a progressive version of a DBMS. Here the data is stored in the tabular form.

Difference between DBMS and RDBMS are:-

Features

DBMS

RDBMS

Storage pattern

DBMS  store data as a file.RDBMS applications store data in a tabular form.
Data storage formIn DBMS, data is stored in either a hierarchical form or a navigational form.In RDBMS, the tables have an identifier which is known as the primary key. The main thing is data here is stored in the tabular form
Type of programIt is the program for managing the databases on the computer networks and the system hard disks.

 

It is the database system that is used for maintaining the relationships among the tables.
NormalizationNormalization is not present in DBMS.Normalization is present in RDBMS.
Security featuresIt does not apply securityHere integrity constraint is defined by RDBMS which allows usage of ACID properties(Atomicity, consistency, isolation, and durability). So it is secure
Software and hardware requirementsLow need for software and hardwareMore need
Relationship with the tablesDBMS makes the use of the file system to store data. So there is no link between any tableTables are used for storing the data values so it is obvious that there would be a link of data between the table as well
Accessibility waysDBMS has to provide some uniform methods to access the stored information.RDBMS system maintenances a tabular structure of the data. The main purpose of this is to access the stored information.
RedundancyData redundancy is thereKeys and index are used so no redundancy of data
Client-server architectureNot supported hereIt supports client-server architecture
Distributed databaseDBMS does not support a distributed database.RDBMS supports a distributed database.
Data volumeDBMS is meant to be for small organizations and deal with small data.RDBMS is designed to handle a large amount of data.
UsersIt supports single userIt supports multiple users.
ExamplesFile system and XML are its examples

MySql, Oracle are the examples

 

Summary of the difference between DBMS and RDBMS

  • DBMS stores data as a file whereas in RDBMS, data is stored in the form of tables.
  • DBMS provisions for single users, while RDBMS is used for multiple users.
  • RDBMS supports client-server architecture but DBMS  does not support client-server architecture.
  • software and hardware requirements are low in DBMS whereas in case of RDBMS it is very high

Conclusion

Both DBMS and RDBMS are database management system but the main difference arises in terms of data storage. In RDBMS tables are deployed for storing the data.
