Building and maintaining an accurate and up-to-date global inventory of hardware, software, and telecommunications assets deployed throughout an organization is described. A global inventory warehouse (GIW) receives an identification and physical location of these assets from multiple source systems. Some of these source systems contain information pertaining to the assets that has been manually entered into the source system by a human administrator. Other source systems, meanwhile, contain information that has been automatically collected by the source systems without human intervention. The GIW receives this information from the source systems and stores it within a GIW database. The GIW database may thus contain a global inventory of all or nearly all of the hardware, software, and telecommunications assets distributed throughout the organization. This database may also contain an identification of physical locations within the organization of all or substantially all of these assets.
