A Database Management System (DBMS) is software that enables the creation, management, and use of databases.
It serves as an interface between end-users and databases, ensuring that data is consistently organized and easily accessible.
Key Features:
1. Data Storage and Retrieval: Facilitates the storing and retrieving of large amounts of data efficiently.
2. Data Security: Ensures that only authorized users can access or modify the database.
3. Data Integrity: Maintains data accuracy and consistency.
4. Concurrent Access: Allows multiple users to access the database simultaneously without conflicts.
5. Backup and Recovery: Provides mechanisms to back up data and recover it in case of failures.
Types of DBMS:
– Relational DBMS (RDBMS): Organizes data in tables (e.g., MySQL, PostgreSQL).
– NoSQL DBMS: Handles unstructured data (e.g., MongoDB, Cassandra).
DBMS plays a crucial role in data management, supporting various applications in fields like banking, education, and healthcare.
