What is the primary function of a Database Management System (DBMS)?

The primary function of a Database Management System (DBMS) is to facilitate the input, storage, search, retrieval, and modification of data. A DBMS acts as an intermediary between users and the database, allowing for efficient and organized management of data. It provides various tools and functions that enable users to perform operations like querying the database for specific information, updating records, or deleting data, all while ensuring data integrity and security.

In contrast, while designing data repositories and creating or organizing data are important aspects of database management, they are not the main functions of a DBMS itself. Rather, these activities occur as part of the broader process of managing data within the system. Mining data for reporting and analysis involves extracting insights and patterns from data, which may be a function of additional tools or layers in data analytics but does not encapsulate the fundamental purpose of a DBMS. Thus, answer B accurately reflects the core capabilities of a DBMS.
