Difference Between DBMS and RDBMS | Difference Between RDBMS and DBMS

The main difference between RDBMS and DBMS (Difference Between DBMS and RDBMS) is that RDBMS saves the data in tables, whereas DBMS saves the application data in the form of files. Tabular form basically means that the data is present in tables and columns. In RDBMS you can access data in relation to other data using tables.

A DBMS is a set of interconnected data in which hams can be accessed from one data to another using applications. RDBMS is a better variant of DBMS designed to remove inefficiencies. The common difference between DBMS and RDBMS is that DBMS just provides an environment where people can easily save data and retrieve it when needed. DBMS also contains redundant data. On the other hand, data redundancy is eliminated by using normalization in RDBMS.

DBMS uses a navigational model whereas RDBMS uses relational model to store and retrieve data.

Difference Between DBMS and RDBMS (Difference Between RDBMS and DBMS)

Saves the data as a DBMS fileRDBMS saves data in tables
Only one data element is accessed at a timeMultiple data elements can be accessed simultaneously
One data element is not related to another data elementIn this, data is saved in the form of tables which are related to each other.
Normalization does not happenNormalization happens
DBMS does not support distributed dataRDBMS supports distributed data
It saves data in navigational or hierarchical formIt uses tabular form to save the data
It is used to handle small dataIt is used to handle huge amount of data.
Data redundancy(redundant) is a common thing in thisKeys and indexes do not have data redundancy

It is used in small organization
It is used in large organizations where a lot of data has to be handled.
Supports single userIt supports multiuser
It takes a lot of time to fetch large dataIn this data fetching is faster than DBMS
There is a low security level for data manipulationThere is multiple level of security in RDBMS
Requires low software and hardwareRequires higher software and hardware
Examples: XML, Microsoft Access, etc.Examples: MySQL, PostgreSQL, SQL Server, Oracle, etc.

Key Differences Between DBMS and RDBMS

  • DBMS uses navigational model whereas RDBMS follows a relational model where data is stored in the form of tables, and there is a relation between those classes.
  • Multiple copies of data can be saved in multiple places in a DBMS, but redundancy is eliminated by using normalization in RDBMS data.
  • Since multiple copies are saved in many places in the DBMS, it is difficult to modify the same file in multiple places. On the other hand, since there is a negligible copy of the data in an RDBMS, it is easy to modify the data.
  • In case of RDBMS data is accessed faster. Conversely, it takes more time to access the data in DBMS.
  • Only integrity constraints are employed in DBMS whereas RDBMS employs schema based constraints and data dependencies.
  • key and indexed are not used in DBMS. On the contrary, in RDBMS these are used to establish relationship between tables.



DBMS and RDBMS are database management systems where RDBMS is more powerful than DBMS. RDBMS is more efficient, faster, and popular and effectively eliminates the limitation of DBMS. DBMS does not provide any security regarding the manipulation of data whereas RDBMS has multiple levels of security of data.
