A Database Management System (DBMS) is software that enables efficient storage, retrieval, and management of data in a structured way.
Two important characteristics of a DBMS are:
(i) Data Integrity: DBMS ensures accuracy and consistency of data through constraints, keys, and validation rules.
It avoids data duplication and maintains the correctness of data across multiple tables.
(ii) Data Security: DBMS provides controlled access to data using authentication and authorization mechanisms.
Only authorized users can access or modify data, ensuring confidentiality and protection from misuse.
These features make DBMS a powerful tool for data-driven applications in every domain.
