Difference between DBMS and RDBMS

By Dinesh Thakur

The full form of DBMS is Database Management System is a software used to store and manage data. The DBMS introduced throughout the 1960s. Additionally, it offers manipulation of the data like insertion, deletion, and updating of the data.

A Database management system is a software system which made up of database and necessary programs to perform database management tasks. Users don’t need to interact with all the data files directly but via a language interface. Utilizing a database management system for data storage and manipulation relieves the users in the accounting duties.

dbms vs rdbmsFor simple data manipulation, users don’t need to write programs; rather, the programs already written in the database that could be invoked by a user by issuing one or more command in a database language. For more complex manipulations programming interface can also include in a DBMS.

The majority of the currently popular DBMS have more complex architecture. Moreover, not only human users but other programs can also interact with the DBMS. In this sequence, the database is commonly known as the back-end, whereas the user program is called front-end. Front-end software can be design to accommodate any individuals or organizations specified data-interaction needs.

We’ll be covering the following topics in this tutorial:

  • What is RDBMS?
  • Difference between DBMS and RDBMS
  • Conclusion

What is RDBMS?

We can declare that an RDBMS (the full form is Relational Database Management System) is an advanced version of a DBMS, even though there are lots of differences between both.

RDBMS Definition: RDBMS meaning that it is a database management system based on the relational model. Relational databases organize data into the tables that are two dimensional. RDBMS examples are Oracle, My SQL, SQL Server, MS-Access, Sybase, Integrase etc.

Most software products in the industry nowadays are equally DBMS and RDBMS compliant. They can keep databases in a (relational) tabular form in addition to a file type, or even both. It means that now an RDBMS program is a DBMS program and vice versa. But, there continue to be significant differences
between RDBMS and DBMS.

Difference between DBMS and RDBMS

Difference between DBMS and RDBMSFollowing are the important differences between DBMS and RDBMS.

SNo.ParameterDBMSRDBMS
1DefinitionDBMS stands for Database Management System, which includes n number of tables there is no relationship between another table.RDMBS stands for Relational Database Management System, which has a relationship with other tables.
2StorageData Store as a file with the metadata.The data will save in the tables.
3NormalizationNormalization isn’t present in DBMS.In RDBMS, the normalization procedure will be present to look at the database table consistency. Data redundancy in DBMS may prevent database normalization.
4Client-ServerIt doesn’t support client-server architecture. It supports client-server architecture.
5Limited AccessData elements need to access individually.Multiple data elements can access at the same time.
6Support for distributed DatabaseDBMS doesn’t support distributed database.RDBMS supports distributed database.
7Data RedundancyData redundancy is expected in this model.Keys and indexes don’t permit Data redundancy.
8Storage LimitationThere are limits to store records in a one database file.There are infinite data stored in a single database file.
9Number of UsersIt supports a single user at the moment.It supports more than one user at the moment.
10Suited forDBMS mostly deals with a small quantity of data.RDBMS layout control a large amount of data.
11Data AlterationData alteration is quite complicated in DBMS.It is simple to alter data in RDBMS.
12Data RelationshipThe Relationship between tables in DBMS is Physical.The relationship in RDBMS is Logical due to the foreign keys.
13Integrity constraintsDBMS doesn’t support Data Integrity.RDBMS support Data integrity.
14Structural IndependenceDBMS doesn’t support Structural Independence.RDBMS support Structural Independence and Advanced Query Capabilities.
15Data RedundancyData redundancy is found in DBMS.It’s eliminated in RDBMS.
16Security SupportThe data in a DBMS doesn’t support Security.RDBMS supports multiple levels of Security on Databases.
17Dr E.F. Codd RulesDbms following less than seven of Codd Rules.RDBMS satisfy more than eight Codd Rules.
18Data Manipulation SecurityDBMS doesn’t apply any security with regards to data manipulation.RDBMS defines the integrity constraint for ACID (Atomicity, Consistency, Isolation and Durability) model.
19ACID ModelDBMS don’t get stored using the ACID(Atomicity, Consistency, Integrity and Durability) model.RDBMS obey the ACID model, and thus the data in RDBMS is fully structured and consistent.
20Index CreationKeys and Indexes not used.In RDBMS, relationship establishment done via keys and indexes.
21Database structureData storage is in hierarchical or navigational format.RDBMS, utilizes a tabular structure where the headers are the column names, and the rows include corresponding values.
22Data AccessDBMS does not provide a uniform method to access the information.Data is accessed quicker in RDBMS than in DBMS.
23Data FetchingIn DBMS, Data fetching is slow to get complex and comprehensive data.The Data fetching is fast due to the relational approach.
24Hardware and software needLow software and hardware requirements. Higher hardware and software requirements.
25Recovery SupportIt doesn’t support recovery.RDBMS helps in recovery of the database in the event of loss of data.
26ExamplesExamples of DBMS are file systems, XML, Microsoft Access, Windows Registry etc.Example of RDBMS is MySQL, PostgreSQL, SQL Server, oracle etc.

Conclusion

From the above differences, we could conclude that RDBMS is much more fast, efficient and more popular. Though DBMS is suitable for smaller organizations, big businesses require RDBMS for its proper function. RDBMS removes the limitations of the DBMS and has quite a few benefits within the DBMS. RDBMS is the complex version of DBMS.
