DBMS vs files
A DBMS manages structured data with querying, concurrency control, transactions, and crash recovery. Plain files lack concurrent safe updates and ad hoc query without rewriting parsers.
- ACID transactions
- Indexes for fast lookup
- SQL/API for declarative queries
Example: two users booking last seat—DB lock/transaction prevents double booking.
