RDBMS vs DBMS
What is DBMS?
DBMS is software used to store and manage data in files. It is simple and works well for single-user applications where performance, security, and relationships are not critical.
What is RDBMS?
RDBMS stores data in tabular form and supports relationships between tables. It uses SQL for querying and ensures data accuracy, security, and efficiency. It is the foundation of most modern database applications.

Two-Minute Drill: Key Differences
-
DBMS is simple and suitable for light workloads, storing data without enforcing relationships.
-
RDBMS is powerful, uses a relational model, supports SQL, and is used in real-world enterprise systems.
-
If your data needs structure, security, and performance, go with RDBMS.
-
Use DBMS only when working with very basic, standalone file-based systems.
