Question

difference between rdbms and dbms

Answer 1

DBMS
DBMS applications store data as file.
In DBMS, data is generally stored in either a hierarchical form or a navigational form.
Normalization is not present in DBMS.
DBMS does not apply any security with regards to data manipulation.

RDBMS
RDBMS applications store data in a tabular form.
In RDBMS, the tables have an identifier called primary key and the data values are stored in the form of tables.
Normalization is present in RDBMS.
RDBMS defines the integrity constraint for the purpose of ACID (Atomocity, Consistency, Isolation and Durability) property.

Answer 2

he key difference is that RDBMS (relational database management system) applications store data in a tabular form, while DBMS applications store data as files. Does that mean there are no tables in a DBMS? There can be, but there will be no “relation” between the tables, like in a RDBMS. In DBMS, data is generally stored in either a hierarchical form or a navigational form. This means that a single data unit will have one parent node and zero, one or more children nodes. It may even be stored in a graph form, which can be seen in the network model.
