What Is The Difference between DBMS and RDBMS

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.

What Is The Difference between DBMS and RDBMS?


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. There are different types of database management systems and some of them are configured for specific purposes.

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.


The database system in which the relationships among different tables are maintained is called Relational Database Management System. Both RDBMS and DBMS are used to store information in physical database.

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. Relational DBMS enforces the rules even though foreign keys are support by both RDBMS and DBMS.

In 1970s, Edgar Frank 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 Is the main requirement of the relational model.

RDMS can be termed as the next generation of database management system. DBMS is used as a base model in order to store data in a relational database system. However, complex business applications use RDBMS rather than DBMS.

DBMS applications store data as file. RDBMS applications store data in a tabular form.
In DBMS, data is generally stored in either a hierarchical form or a navigational form. In RDBMS, the tables have an identifier called primary key and the data values are stored in the form of tables.
Normalization is not present in DBMS. Normalization is present in RDBMS.
DBMS does not apply any security with regards to data manipulation. RDBMS defines the integrity constraint for the purpose of ACID (Atomocity, Consistency, Isolation and Durability) property.
DBMS uses file system to store data, so there will be no relation between the tables. in RDBMS, data values are stored in the form of tables, so a relationship between these data values will be stored in the form of a table as well.
DBMS has to provide some uniform methods to access the stored information. RDBMS system supports a tabular structure of the data and a relationship between them to access the stored information.
DBMS does not support distributed database. RDBMS supports distributed database.
DBMS is meant to be for small organization and deal with small data. it supports single user. RDBMS is designed to handle large amount of data. it supports multiple users.
Examples of DBMS are file systems, xml etc. Example of RDBMS are mysql, postgre, sql server, oracle etc.
