Difference Between DBMS and RDBMS – Its Revealed!

DBMS stands for Database Management System, while RDBMS is the acronym for Relational Database Management System. RDBMS and DBMS are used for the storage of data. They are capable of storing sensitive data with ease. The method of storing the data for both of these vary from each other. Data management is a crucial task, and the system that serves well in this regard ensures to gain more value and repute. Let’s learn the Difference Between DBMS and RDBMS!


Form of Data Storage 

One of the powerful and significant data management systems is RDBMS. It is used worldwide and aims to store the data and manage it in tabular form. No matter how huge the data is, RDBMS will function well to store it in the form of columns and rows. These are known as attributes and tuples. However, contrary to this, DBMA is responsible for storing the data in the file format. 

Users and Security

RDBMS is the latest and splendid approach that supports multiple users. However, DBMS is the system that supports a single user. The software system of RDBMS is easy to be normalized while there is no support for normalization in DBMS. DBMS does not offer security, while RDBMS comes up with a huge deal of security. The multilevel security is due to object level, Command, and OS.

Client-Server Architecture

As DBMS allows only the single user to use, operate, store and access the data, so it does not support other users. So, it does not have an association with the client-server architecture. However, contrary to this, the client-server architecture is well supported by RDBMS. 


The software requirement for DBMS is not that much. Hence, users can use this software system with much ease. Just like the software, it also does not have many hardware requirements. On the contrary, RDBMS demands more software and hardware and is known to have high requirements.

Data Redundancy

Both DBMS and RDBMS differ in the features of data redundancy. Data redundancy is not allowed in the case of RDBMS. Both indexes and keys prevent data redundancy in RDBMS. However, data redundancy is more frequent and common in DBMS.

Type of Program

DBMS is such a worthy program that is responsible for storing and managing the database on the system hard disk and computer networks. At the same time, RDBMS is a fabulous data system that efficiently maintains the relationship among tables.

Data Quantity

The data size varies from one project to another. It is significant to know which software system is compatible with large data or small data. When you are having a smaller data quantity than in this case, DBMS is the worthiest system. However, when the research data or company data is available in large amounts, then no worries at all. RDBMS is well suited to handle huge data with ease.

Data Fetching

The large and complex data is quite tough to retrieve in DBMS. DBMS takes much time and becomes slower when it has to fetch complex data. While, in RDBMS, the fetching of data is easier and rapid. It is because of the feature of the relational approach.
