DBMS Vs RDBMS
DBMS and RDBMS both are used to store information in physical database but there are some remarkable differences between them.
RDBMS (relational database management system) applications store data in a tabular form, while DBMS applications store data as files. We can say that a RDBMS is an extension of a DBMS.
The main differences between DBMS and RDBMS are given below:
DBMS |
Key |
RDBMS |
| DBMS stands for DataBase Management System |
Definition |
RDBMS stands for Relational DataBase Management System. |
| In DBMS, each data elementsare to be accessed individually. |
Data Access |
In RDBMS, multiple data elements can be accessed at same time |
| Data is stored as file. |
Data Storage |
Data is stored as tables. |
| There is no relationship between data in DBMS. |
Relationship |
Data is present in multiple tables which can be related to each other. |
| DBMS deals with small quantity of data. |
Data Quantity |
RDBMS deals with large quantity of data. |
| DBMS has no support for distributed databases. |
Distributed database |
RDBMS supports distributed databases. |
| Normalization cannot be achieved. |
Normalization |
Normalization can be achieved. |
| Inefficient, error prone and insecure. |
Transaction management |
Efficient and secure. |
| Does not used. |
Keys and indexes |
To establish relationship keys and indexes are used in RDBMS. |
| DBMS supports single user at a time. |
User |
RDBMS supports multiple users at a time. |
| Data Redundancy is commonin DBMS. |
Data Redundancy |
Data Redundancy can be reduced using key and indexes in RDBMS. |
| DBMS provides low security during data manipulation. |
Security |
RDBMS has multilayer security during data manipulation. |
| Modification in data is complex. |
Modifiability |
Modification in data is easy and simple. |
| Not employed |
Schema-based constraints and data dependencies |
Employed in RDBMS. |
| MSAccess, LibreOffice Base, FoxPro, Dbase. |
Example |
Oracle, SQL Server. mysql, MariaDB, SQLite. |
Conclusion
The DBMS and RDBMS are the database management system where RDBMS is the successor of DBMS. RDBMS is more efficient, fast, and popular and effectively eliminates the limitations of DBMS. DBMS does not enforce any constraints and security concerning manipulation whereas RDBMS defines integrity constraints with intend of holding ACID property.
I hope this post helps you to understand all the comparisons between “DBMS and RDBMS”.
Keep Learning 🙂
Though i have learned about it but after read your articles, i just realized the amount of knowledge that i missed. Thank for your shared. Hildegaard Wallie Sharman
When some one searches for his essential thing, so he/she wants to be available that in detail, so that thing is maintained over here.
Hello. This post was really remarkable, particularly because I was investigating for thoughts on this matter last Friday. Karel Teddy Chemosh
Good post. I learn something totally new.
Heya i amm for the first time here. I came across this board and I find It really useful & it helped me out much.
You made certain fine points there. I did a search on the theme and found a good number of persons will agree with your blog.
