Difference in DBMS and RDBMS

Let’s see, The Difference in DBMS and RDBMS but first Let’s understand what is DataBase?


The software application that enables the users to store the data is known as a database. In database architecture, there are different implementations and theories in order to store physical data.

The database which stores data in the tables that have relationships with other tables in the database is called RDBMS or Relational Database Management System.


However, in DBMS or Database Management System, there are no relationships among tables. In DBMS, the tables are not linked to each other.


What is DBMS?

DBMS is defined as the software program that is used to manage all the databases that are stored on the network or system hard disk.

DBMS is available in different forms as a tool that is used to manage databases. Some popular DBMS solutions include DB2, Oracle, FileMaker and Microsoft Access. Using these products, privileges or rights can be created that can be specific to particular users.

It means that the administrators of the database can grant specific rights to some users or assign different levels of administration.


Every DBMS has some fundamental elements. First is the implementation of the modeling language which defines the language used for each database. Second, DBMS also administers the data structures. Data query language is the third element of a DBMS.

Data structures work with data query language in order to make sure that irrelevant data cannot be entered into the database used in the system.


What iS RDBMS?

The database system in which the relationships among different tables are maintained is called Relational Database Management System (RDBMS).


RDBMS solution is required when large amounts of data are to be stored as well as maintained. A relational data model consists of indexes, keys, foreign keys, tables and their relationships with other tables.


In the 1970s, E F Codd introduced the theory of relational database. Thirteen rules were defined by Codd for this relational theory or model. Relationships among different types of data are the main requirement of the relational model.


The RDBMS consists of the following –

  • Collections of Objects or Relations
  • Set of Operator to act on the Relations
  • Data integrity for accuracy and Consistency



  • The relationship among tables is maintained in an RDBMS whereas this, not the case DBMS as it is used to manage the database.

  • DBMS applications store data as file while RDBMS applications store data in a tabular form.

  • DBMS is used for simpler business applications whereas RDBMS is used for more complex applications.

  • Normalization is not present in DBMS while Normalization is present in RDBMS.
