The present invention provides generalized database tables to implement the classifications of Resource Type, Resource Specification, and Resource Instance, supplemented by individual tables specific to each type of resource, and by the associations and dependencies between them. More specifically, this invention provides database tables comprising a group of structures including Resource Type, Resource Specification and Resource Instance. The Resource Instance is a representation of an individual computing resource, each Resource Instance relates to a physical or logical instance of one Resource Specification. A Resource Specification is a collection of features and functions of a given resource, belonging to one Resource Type which can have zero, one or more resource instances associated with it. A Resource Type, being the highest level of the Resource Model can have zero, one or many resource specifications associated with it.
