The role of a database management system (DBMS) is to facilitate the creation, manipulation, and administration of databases. A DBMS provides a systematic way to store, retrieve, and manage data efficiently and securely. It enables users to perform various operations such as querying, updating, and ensuring data integrity. By providing a framework for data storage, DBMSs support features like data concurrency, transaction management, and access control. They play a crucial role in business applications, enabling organizations to analyze data for decision-making, manage large datasets effectively, and ensure that data is consistent and readily available.
