What is a feature of a Database Management System (DBMS)?

A Database Management System (DBMS) is designed to facilitate efficient database access while maintaining data security. This feature is crucial because it allows multiple users to retrieve and manipulate data without compromising the integrity and confidentiality of that data. Security measures typically include user authentication, data encryption, and authorization protocols, ensuring that only authorized personnel can access sensitive information.

The other options do not accurately represent the core features of a DBMS. For instance, promoting data duplication contradicts the fundamental goal of a DBMS, which is to minimize redundancy and enhance data integrity. The restriction of user access to data is a component of security, but it is not as comprehensive as facilitating access while ensuring security. Lastly, the elimination of data processing is not a feature of a DBMS; on the contrary, a DBMS is essential for processing data efficiently, organizing it, and providing mechanisms for retrieval. Thus, the emphasis on secure access highlights a primary function of DBMSs in managing data within organizations.
