What functionality does a Database Management System (DBMS) provide?

A Database Management System (DBMS) provides critical functionalities that include the creation of reports and the enforcement of rules, which are fundamental to effective data management. The ability to generate reports allows users to extract meaningful information from the stored data, providing insights that can drive decision-making and operational improvements. Furthermore, a DBMS facilitates the establishment of rules related to data integrity and access control. This ensures that the data remains accurate, secure, and compliant with relevant policies and regulations.

While reporting and rule enforcement are core functionalities of a DBMS, other options relate to aspects that may be outside the primary scope of a DBMS. For instance, visualization deals more with data presentation tools, and machine learning falls under advanced analytics and data science realms, which may utilize data stored in a DBMS but are not standard functions of a DBMS itself. Similarly, hosting data in the cloud pertains to data storage solutions and infrastructure rather than the fundamental operations a DBMS performs.
