Abstract: A unique data label is affixed to each tracked asset and a unique data label for each location in the enterprise, both real and virtual locations. Location history data of the asset is related to other asset data in a relational data base. Assets typically include system components down to the least repairable/replaceable unit (LRU). The data label, in the preferred embodiment of the invention, is a code label using a code that ensures each label is unique to the asset or location to which it is attached. Here the word location is an inclusive term. It includes the geographical location and the identity of the building in which the asset is housed. Location also includes the identity of the system of which a component is a part and, if relevant, location within the system. It includes also any real or virtual location of interest for subsequent analysis and is ultimately defined by the nature of the system being tracked.
