File System vs DBMS

Reading Material & Notes

File System vs DBMS

Traditional file systems store information in separate files, while a DBMS provides an organized system for managing related data.

Feature	File System	DBMS
Data Redundancy	Generally higher	Can be reduced
Security	Limited	Advanced access control
Data Sharing	Limited	Supported
Backup and Recovery	Usually application dependent	Built-in mechanisms available
Data Integrity	Limited	Constraints can be applied
Concurrent Access	Limited	Supported

Conclusion

DBMS is more suitable for complex applications where data security, consistency, sharing and concurrent access are important.
