RDBMS Vs DBMS

What Is DBMS?

A Database Management System (DBMS) is a software developed in the 1960s for storing, managing, and manipulating data. It handles tasks like defining, creating, modifying, and managing databases, enabling business applications to extract and preserve relevant data.
XML, File system, window registry, etc are some of the examples of database management systems.

What Is RDBMS?

RDBMS, or relational database management system, is a more powerful DBMS system. It was established in the 1970s.It is a robust data management system, utilized extensively all over the world.
Oracle, MYSQL, SQL Server, etc are some of the examples of Relational Database Management Systems.

Even though DBMS and RDBMS are both used to store data in physical databases, there are several notable distinctions between the two.

Below are some of the parameters based on which DBMS and RDBMS can be differentiated:

Data storage and structure

• In DBMS, files are used to store data. Either a hierarchical structure or a navigational structure is used to organise it.
• Data is kept in tables in RDBMS. There is no hierarchy; rather, a relational approach is used. The headers are in the columns, and the values are in the rows.

Number of Users

• A single user is all that a database management system can accommodate.
• Multiple users can access the databases using relational database management systems.

Hardware and Software Requirement

• Minimum hardware and software specifications are needed for DBMS.
• RDBMS has more complex software and hardware requirements than traditional DBMS.

Data Client-Server

• The client-server architecture is not supported by DBMS.
• RDBMS supports client-server architecture

Data Redundancy

• The DBMS version adds data repetition and redundancy.
• RDBMS uses keys and indexes to eliminate data redundancy hence saves time and resources.

Data Relationships

• There are no relationships between the data maintained in the database management system.
• RDBMS establishes relationships between data stored in tables using foreign keys for relating tables with each other.

Distributed Databases

• Database distribution is not supported by DBMSs.
• Distributed database functionality is provided by RBMS.

Conclusion:

The structural differences between DBMS and RDBMS are significant. Since DBMS was the first database management system, it lacks capabilities for data security, data integrity, access to data, multiple-user access, and quicker data retrieval. The RDBMS ensures there are no data redundancies or inconsistencies and is quicker and more effective. In short, there is no absolute standard that establishes RDBMS as the greatest type of database management system available. Despite the fact that there are various kinds of database management systems, RDBMS is by far the best and moves more quickly than DBMS.
