What is the main function of Dynamic Management Views (DMVs)?

The main function of Dynamic Management Views (DMVs) is to offer insights into the current state and performance of the database. DMVs are system views in SQL Server that provide real-time data about the internal workings of the database engine. They enable database administrators to monitor and analyze the performance of various database components, such as sessions, queries, server health, and system metrics.

By querying DMVs, administrators can gain valuable information that assists in performance tuning, diagnosing issues, and understanding workload patterns. This capability is essential for maintaining optimal performance and ensuring the stability of SQL databases.

While other functions mentioned in the choices, such as administrative tasks, creating backups, and managing user permissions, are essential aspects of database management, they do not fall under the primary purpose of DMVs. Their role is specifically tailored towards providing insights rather than performing these other administrative functions.
