What is a Database Management System (DBMS)?
A Database Management System (DBMS) is software that enables users to efficiently store, retrieve, manage, and manipulate data in a structured format. It acts as an interface between the database and its users or application programs, ensuring data is consistently organized and easily accessible.
Key Components of a DBMS
- Database: A structured collection of data (e.g., student records, inventory).
- DBMS Software: The engine that manages the database (e.g., MySQL, Oracle).
- Query Language: Typically SQL, used to interact with the database.
- Users: Includes database administrators, developers, and end-users.
Why Use a DBMS?
- Reduces Data Redundancy: Avoids duplication by centralizing data.
- Ensures Data Integrity: Maintains accuracy and consistency.
- Supports Concurrent Access: Multiple users can access data simultaneously.
- Enhances Security: Controls access through permissions and roles.
- Provides Backup & Recovery: Protects data from loss or corruption
