Definition - What does Windows Management Instrumentation (WMI) Database mean?
A Windows Management Instrumentation (WMI) Database is a repository of software drivers, applications and extensions available in the Windows operating system.

Techopedia explains Windows Management Instrumentation (WMI) Database
WMI Database allows system administrators to monitor, manage and measure performance and operational statistics through the use of application programming interfaces (API). WMI Database's primary function is to provide infrastructure management services for computing operations management.
WMI Databases store different providers' products or entities' basic meta-information, such as the definition and implementation of the provider model, the type of provider and the hosting model. Although only tested and accepted providers are registered within the WMI Database, after the creation of a basic model the product’s template and code snippets are created so that they can be accessed through software application and system services.
