What is a vital role of database management systems in data handling?

The vital role of database management systems (DBMS) in data handling encompasses various functions, but one of the most significant is ensuring data security. A DBMS is designed to provide mechanisms that restrict unauthorized access and maintain the integrity and confidentiality of the data. Data security measures may include user authentication, encryption, access control lists, and audit trails, which help protect sensitive information from breaches and unauthorized modifications.

While selectively printing data can be a function performed within a database system, it does not capture the essence of what a database management system is primarily designed to do. Storing data in physical formats refers to how data is stored and accessed but does not highlight the management and control aspects. Elimination of data, such as deletion, is certainly a function of a DBMS, but it is not considered a vital role; rather, it is more of a procedural action that can be undertaken within the broader context of managing data.
