Ultimate Difference Series; DBMS vs RDBMS


Toodles, readers, we are overwhelmed with your love and decided to put on the notch in our famous Ultimate Difference Series. Today, we are going to draw the difference between the two Database management systems. Role of both management systems is to handle the data in the most relevant and effective manner, however, the approach adopted by both systems are totally different. So, let’s don’t waste more time and start our difference battlefield.


DBMS is a short form of the Data Base Management System. This management system is a computer-based system launched in the 1960s. It is basically a computer software which is designed to store any kind of data which can further manipulate and update the data. The data can be any form or shape, it can be easily manipulated using tools like insertion, deletion, updating.

The data can be about a person, a company, or it can be about any object DBMS can manage all. It has several components which help data manager to manage the data. The major components of the database management system are; external interface, database language engine, query optimizer, database engine, storage engine, etc.,


RDBMS can be expanded as Relational Database Management System. This system was introduced decade later than the DBMS, during the 1970s. It is a database management software which is used to store the data that can be only stored in the tabular form. Data is stored in the rows and columns also known as tuples and attributes respectively. RDBMS can also be called as some sort of extension for the database management system.

So, in a manner, every RDBMS is a DBMS. But, not every DBMS is an RDBMS. For DBMS to become an RDBMS, have to satisfy at least 6 to 7 rules out of the 12 rules defined by E.F. Codd, till date no RDBMS has satisfied all the rules.

Difference Between DBMS & RDBMS

Storage unit.

In DBMS, data is stored in the shape of objects or in the layout of files. Whereas in RDBMS, data is stored in the unit called relations commonly known as tables.


It is not possible to normalize the data in the DBMS. It is indeed possible to normalize in the RDBMS.


The data in the DBMS is stored in the general hierarchical form. Data in the relational database management system is stored independently but are interlinked with some constraints.


There are not constraints available in the DBMS, which means the management system isn’t much secured. However, in the RDBMS, data is interlinked through numerous constraints which ensures the data integrity and security. That’s why RDBMS offers more security than the database management system.


There is no relationship with the stored data can be established in the DBMS. On the contrary, RDBMS is all about establishing a relationship with the stored data files using constraints.


Well, there are no specific rules or properties followed by the DBMS while manipulating the data. In RDBMS, a proper set of rules are followed called ACID stands for Atomicity, Consistency, Integrity, Durability properties for data security.


DBMS doesn’t use the support of distributed databases, RDBMS support distributed databases.

Data size.

DBMS generally deals with the small data generated by the single users. Whereas RDBMS covers large data generated by multiple users. The selection of the database management system depends on the requirement of the users only.


DBMS examples are; file systems,xml,etc. RDBMS examples; mysql, sql server, oracle etc.

Well, that was our yet another amazing difference series, if you like it then please let us know.
