What is a DBMS?
A Database Management System (DBMS) is software
designed to store, retrieve, and manage data in
databases. It ensures that data is organized and easily
accessible.
ACID Properties
Atomicity: All operations in a transaction
are completed, or none are.
Consistency: Data remains in a valid state
before and afterthe transaction.
Isolation: Transactions do not interfere
with each other.
Durability: Once a transaction is committed, it
remains saved even during power failure.
DBMS vs. File System
Unlike traditional file systems, a DBMS provides:
Reduced data redundancy.
Enhanced data security.
Support for multiple users simultaneously.
