Features of DBMS

⟹ Structure: Where data is structured in hierarchical form in a DBMS, data is structured in tabular form in a RDBMS.

⟹ User capacity: A RDBMS is capable of operating with multiple users. DBMS can only manage one user at a time.

⟹ Software/hardware requirements: A RDBMS has greater software and hardware requirements.

⟹ Programs managed: DBMS maintains databases within the computer network and system hard disks. A RDBMS manages the relationships between its incorporated tables of data.

⟹ Data capacity: A DBMS is capable of managing small amounts of data and a RDBMS can manage an unlimited amount of data.

⟹ Distributed databases: A DBMS does not provide support for distributed databases while a RDBMS does.

⟹ ACID implementation: A RDBMS bases the structure of its data on the ACID (Atomicity, Consistency, Isolation, and Durability) model.
