The primary role of a database management system (DBMS) is to store, manage, and retrieve data efficiently. It acts as an interface between users and the database, ensuring data integrity, security, and accessibility. A DBMS allows multiple users to access and manipulate data concurrently while maintaining consistency. This technology supports various applications by facilitating complex queries and data analysis, making it essential for businesses that rely on data-driven decisions. It also aids in data backup and recovery.
