Which of the following is a core function of a database management system (DBMS)?

A database management system (DBMS) primarily serves as the intermediary between users and their data, providing a structured environment for managing data efficiently. The core function of data storage and retrieval is essential because it enables the organization, manipulation, and access of vast amounts of data in a systematic way. A DBMS supports various operations, such as creating, reading, updating, and deleting data, which are crucial for the effective management of databases.

Data visualization, while important in understanding data through graphical means, is not a primary function of a DBMS. Visualization tools often work in conjunction with a DBMS, pulling data from it, but do not fall under its core functions.

Data encryption enhances security by protecting data, especially sensitive information, but it is not considered a fundamental operation of a DBMS. Rather, it is an additional feature that can be implemented alongside the DBMS operations.

Data compression helps save storage space by reducing the size of the data files but is again not a core function of a DBMS. This feature may be provided by some systems, but it does not define the essential capabilities of database management.

In summary, the primary responsibilities of a DBMS revolve around the effective storage, organization, and retrieval of data, which is why data
