A RDBMS stores data in the forms of the tables. |
DBMS supports single users. |
RDBMS supports multiples users. |

DBMS has low software and hardware requirements. |
RDBMS has higher hardware and software requirements. |
In DBMS, data redundancy is common. |

The support of integrity constants is just not present in DBMS. |
RDBMS has the support for integrity constants. |
DBMS does not support normalization. |
RDBMS can supports normalization. |

There is a lack of security in the DBMS model of storing data, |
There are several log files created, which automatically increases the security of the data stored in the RDBMS model. |
DBMS needs minimum software and hardware requirements. |
In RDBMS, hardware and software requirements are higher than the classic DBMS. |
In DBMS, there is no relationship between data |
In RDBMS, Data is stored in the form of tables which are related to each other with the help of foreign keys. |
Data elements need to access individually. |
Data can be easily accessed using SQL query. Multiple data elements can be accessed at the same time. |
It is specially designed to create and maintain data and enable the individual business application to extract the desired data. |
