What is the Differences Between DBMS and RDBMS

In the earlier days, storing large amounts of data was difficult. But as technology kept advancing, it provided us with a magical database. A database is usually an organized collection of arranged data which users can access, update, or control. The data in the database can be placed into rows, columns, or tables. But as the need for more storage space increases, it has been evident that technology needs database management that could maintain, modify, protect, and retrieve the real-time database.

At this point, database management (DBMS) and relational database management systems(RDBMS). DBMS is like a software program that can maintain, create, and control database access, whereas DBMS's advanced version is RDBMS. Even though both are used to store physical data, they have their own differences. To find the difference between DBMS and RDBMS to find out how they differ for understanding them better.

What is DBMS?

A Database Management System or DBMS is a software application that acts as an interface between the user, various applications and the database for the purpose of analyzing and storing the data. This system is responsible for retrieving, creating, managing and updating the data in a synchronized manner. For doing the same, database languages are used by a database management system.

Features of Database Management Systems

Here are the features which DBMS offers -

Database customization.
Organizing the data.
Minimum data duplication and redundancy.
Usage of query languages.
Maintenance of data integrity.
Metadata management.
Saves storage space and cost.

How DBMS Works?

DBMS works as follows -

It allows data manipulation in the user's database files, including updating, creating, and editing when required.
It organizes your database's files and gives end users more control and access to their data.
It can also store and retrieve the needed data from the user's database.
Benefits of using DBMS

Benefits of Using DBMS

Keeps track of data inventory, customers, and employees.
Keeps operations of business running as planned.
Maintains the performance of the application and database.
Automate the data procedures and processes.
Store and organize a variety of unique types of data.

Advantages of DBMS

Below are the advantages of DBMS.

Better data integration
Minimized data inconsistency.
Data security.
Faster data access.
Provides best data integrity.

Drawbacks of DBMS

So here are the disadvantages of DBMS

Increases cost.
High complexity.
Currency maintenance.
Huge size.
Database failure.
Difficult backup and recovery.
Lower efficiency.
Increased vulnerability.

What is RDBMS?

If we talk about the Relational Database Management System (RDBMS), it is a type of DBMS which is based on the Relational Model. Majority of the databases that are used presently are designed on the relational database model itself.

It is the prominent database system among various organizations across the world. It offers a dependable method that you can use to store and retrieve huge amounts of data. You can do it while providing a combination of ease of implementation and system performance.

Features of Relational Database Management Systems

RDBMS has four essential features, termed in short form as ACID -

Atomicity - It keeps data accurate
Consistency - The database state should stay consistent throughout the transaction
Isolation - Here, each transaction is separate and not dependent on others.
Durability - You can recover the data from a failed transaction.

How RDBMS works?

RDBMS stores the data in a table form. Each system has a different number of tables, and every table has a unique primary key. This primary key is necessary to recognize each table. The table has rows and columns. The rows represent horizontal entities or records which possess information for an individual entry. Columns are referred to as vertical entities containing data related to a particular field.

Before creating a table. RDBMS has to check the following constraints.

Foreign keys
Primary keys
Not null
Check
Data integrity.

Benefits of using RDBMS

Here are the merits of utilizing RDBMS

Prevents the redundancy of data.
Multi-person access.
Privilege control and data security.
Easier maintenance.
Ease of use.
Network access.

Advantages of RDBMS

The following are the RDBMS Advantages

It is secured in nature.
It is easier to utilize.
It offers multiple interfaces.
It offers the best physical database independence.
It performs data manipulation.
It provides better data integrity.

Drawbacks of RDBMS

Maintenance problem.
Costly to set up and maintain.
Lack of scalability.
Complexity in structure.
Reduction in performance over time.

Since DBMS and RDBMS share the same concept, i.e. they both are Database Management systems, people usually confuse between them. This article will discuss the difference between dbms and rdbms in sql.

Difference Between DBMS and RDBMS

In this section, we will discuss all the parameters in which these two differ from each other. So here we compare dbms vs rdbms

Category	DBMS	RDBMS
Definition	A software system that manages and maintains a database	A type of DBMS that stores and manages data in a relational structure
Data Model	Hierarchical or network model	Relational model
Data Storage	Stores data in files, with each file containing multiple records	Stores data in tables, with each table containing multiple rows and columns
Data Access	Uses navigational access to retrieve data	Uses SQL (Structured Query Language) to retrieve data
Data Integrity	No inherent data integrity checks	Enforces referential integrity, constraints, and triggers to maintain data integrity
Scalability	Limited scalability, as it cannot handle large amounts of data or complex queries	Highly scalable, as it can handle large amounts of data and complex queries
Security	Limited security, as it does not provide advanced security features	Provides advanced security features such as access control, encryption, and authentication
Normalization	Normalization does not exist	Normalization exists
Distributed Database	Distributed databases are not supported	Distributed databases are supported
Relation Between Tables	Deploys file system for storing the data, therefore there is no relation between the data tables	Stores the data in tabular form and hence a relation exists between the tables
Number Of Users	Supports single user only and is generally used in small scale organizations	Supports multiple users and is preferred by large organizations
Examples	Examples include file systems such as XML and Microsoft Access	Examples include MySQL, PostgreSQL, SQL Server, Oracle, etc.

Conclusion

When it comes to deciding which database management system is best for your organization, it's better to find the difference between dbms and rdbms. Then you need to keep in mind the size of your organization and the amount of data which needs to be managed. However, comparing rdbms vs dbms will let you know that RDBMS is more secure and stores data in a structured manner. Choosing RDBMS is better than choosing DBMS. This allows you to know whether DBMS is better or RDBMS is best.

FAQ:

1. What is RDBMS and example?

RDBMS is a relational database management system that is oriented on data or relational models. Examples are MySQL, SQL server, Oracle etc.

2. Is SQL a DBMS or RDBMS?

It is neither an RDBMS nor DBMS. SQL is actually a programming language utilized to query the data on either of the database management systems.

3. Why is DBMS better than RDBMS?

When you find the difference between dbms and rdbms, you will understand that DBMS is better than RDBMS. It is because there is data redundancy in DBMS, but in RDBMS, redundant data is not possible due to indexing present.
