Difference between DBMS and RDBMS

A DBMS has to be persistent, that is, it should be accessible when the program created the data ceases to exist or even the application that created the data restarted. A DBMS also has to provide some uniform methods independent of a specific application for accessing the information that is stored. Ex- Foxpro

RDBMS is a Relational Data Base Management System Relational DBMS. This adds the additional condition that the system supports a tabular structure for the data, with enforced relationships between the tables. This excludes the databases that don't support a tabular structure or don't enforce relationships between tables.Ex- oracle, SQL

1)DBMS does not impose any constraints or security with regard to data manipulation. It is user or the programmer responsibility to ensure the ACID PROPERTY of the database. While RDBMS defines the integrity constraint for the purpose of holding ACID PROPERTY.

2)In DBMS Normalization process will not be present.While in RDBMS, normalization process will be present to check the database table consistency.
