APPLICATION PROGRAMMING INTERFACE FOR EFFICIENT OBJECT INFORMATION GATHERING AND LISTING

An information system has a database having distinct object structures that store information about corresponding operating components of the system. An association structure describes many-to-many relationships among the components. Targeted requests for information about first objects are satisfied by obtaining information from a first object structure as well as information about associated objects from the second object structure. Bulk requests for information about a large number of objects are handled differently, using a lookup structure that associates the first objects with limited information of the associated second objects, such as externally visible names which would be meaningful to a requestor. Thus response can efficiently provide full information about all first objects as well as limited but useful information about all associated second objects, avoiding traversals of the association structure and corresponding interrogations of the second object structure.
