Answer» The key differences between Relational Database Management SYSTEMS (RDBMS) and Database Management Systems (DBMS) are as follows: | RDBMS | DBMS |
|---|
| They store data in the form of tables of rows and columns | They store data in the form of files. | | Related data are stored in a single table. | There is no relationship between the data stored in a single file of DBMS. | | Many data items can be FETCHED simultaneously using mechanisms like grouping, ETC. | Only a single data item can be fetched at a particular point of time. | | Relational tables can be normalized due to which Data Redundancy can be reduced. | No concept of Normalization and hence Data Redundancy is PREVALENT. | | Distributed databases are supported by RDBMS. | DBMS does not support distributed databases. | | It can support multiple users at the same time (concurrent access is possible). | Only one user can use the DBMS at a particular time. | | Faster data fetching due to the relational approach. | Data fetching is normally very slow since there is no relation between data in a file. | | It has a lot of hardware and SOFTWARE needs. | Very few hardware and software needs are there in it. | | Data is more secure in RDBMS than in DBMS as various security mechanisms are implemented at various levels in it. | Data is highly insecure in DBMS. | | Examples of RDBMS include Oracle, MySQL, Postgre, etc. | Examples of DBMS include XML, Window Registry, etc. |
