DBMSs create, store, manage, update, and retrieve data from databases, while RDBMSs create and manage data in tabular format to make retrieval and updating more efficient.
1
Comparison Based on Storage
DBMS store data in files and in a hierarchical or a navigational form, whereas RDBMS store data in tables and follow a relational model rather than a hierarchical form.
2
Comparison Based on Distributed Databases
DBMS does not support distributed databases, whereas RDBMS supports distributed databases that can be stored in different locations.
3
Comparison Based on Data Integrity
RDBMSs support data integrity constraints, which are necessary for maintaining accuracy and consistency in databases, while DBMSs do not support such constraints.
