A location model is a hierarchy that organizes the locations discovered for a business domain. A location hierarchy places a general location or location category at the highest level in the model, this is referred to as the model's root. More specific locations within the general location are organized below it. The lower in the hierarchy the location appears, the more specific the location
A number of location hierarchies may be created for the business domain, categorized by subject. One model may organize the facilities of the business. For example, the highest locations may be business sites, which contain specific buildings, which contain specific floors, which contain specific work areas, etc. Another location hierarchy may relate customer locations. For example, a business's markets may be organized into countries, which contain specific regions, which contain specific states, etc.
