Some embodiments provide a system for processing relationship data that expresses relationship between various entities. In some embodiments, the entities are entities associated directly with an enterprise. The entities in some embodiments described below also include entities associated indirectly with the enterprise through other entities. In some embodiments, the system consolidates disparate relationship data sets that relate to the same set of entities. For instance, in some embodiments, the system includes several data storages that store relationship data. For at least two entities, at least two different data storages store two different relationship data sets that differently express the relationship between the two entities. The system includes a hierarchy manager that receives the two different relationship data sets and consolidates the two different relationship data sets into one relationship data set that best expresses the relationship between the two entities.
