Difference Between DBMS and RDBMS

DBMS Vs. RDBMS: In this tutorial, we will learn about the differences between DBMS and RDBMS. By Pratishtha Saxena Last updated : May 27, 2023

A database is an organized collection of structured data that is stored and managed in a systematic manner. It is designed to efficiently store, retrieve, update, and manage vast amounts of information. Databases are used in various applications, ranging from small-scale personal projects to large enterprise systems.

A database typically consists of one or more tables, where each table represents a specific entity or concept. Tables are composed of rows and columns, with each row representing a record or instance of the entity, and each column representing a specific attribute or property of the entity. The tables are interconnected through relationships, allowing data to be linked and related across multiple tables.

Overall, databases play a crucial role in organizing and managing structured data, enabling efficient data storage, retrieval, and manipulation for various applications and industries.

What is DBMS?

A Database Management System (DBMS) is software that provides an interface for managing databases. It serves as an intermediary between users or applications and the underlying database. DBMS facilitates the creation, modification, organization, and retrieval of data from the database. It handles tasks such as data storage, security, concurrency control, and query processing.

Examples of popular DBMSs include MySQL, Oracle Database, Microsoft SQL Server, and SQLite.

What is RDBMS?

A Relational Database Management System (RDBMS) is a specific type of DBMS that follows the principles of the relational model. In an RDBMS, data is organized into tables consisting of rows and columns. Tables are related through defined relationships, typically using primary keys and foreign keys. RDBMSs provide a structured approach to managing data, ensuring data integrity, and supporting the SQL (Structured Query Language) for querying and manipulating the data.

Examples of RDBMSs include Oracle Database, MySQL, Microsoft SQL Server, and PostgreSQL.

The Difference Between DBMS and RDBMS

The key difference between DBMS and RDBMS lies in their data organization models. DBMS is a broader term encompassing various data models, while RDBMS is a specific type of DBMS that strictly follows the relational model. RDBMSs provide additional features, such as referential integrity, to enforce relationships between tables and ensure data consistency.

1 DBMS stands for database management system and has single user support RDBMS stands for Relational database management system and has multi users support
2 DBMS introduced during 1960's by Edgar F. Codd RDBMS introduced during 1970's by codd
3 DBMS represent data as a file RDBMS represent data in a tabular form
4 DBMS don't provide normalization facility RDBMS provides normalization facility
5 In case of DBMS there is no relationship between tables In case of RDBMS there is relationship between two or more than two tables
6 DBMS has several components like query optimizer, database language, database engine RDBMS has three components like Data Structure, Data Integrity, Data Manipulation
7 There are many types of DBMS like:
  • Object Oriented Database Management system (OODBMS)
  • Relational Database Management System (RDMS)
  • Hierarchical Database Management System
  • Network Database Management System
There are many types of RDBMS like:
  • Oracle
  • Mysql
  • Microsoft SQL Server
  • PostgreSQL
  • IBM DB2
8 DBMS is basically made for small organization (it means handles limited amount of data) RDBMS is basically made for large organization (it means handles unlimited amount of data)
