Domain HierarchyCanonical sounds a bit religious, and perhaps it is… I refer to canonical information models that rule the flow and interpretation of data in the enterprise. Whether there is an explicit information model or not, there is a model: and it’s based on the aggregate portfolio of information assets.  The less explicitly the model is managed and used to govern the implementation and integration of automated capabilities, the more chaotic will be the flow and interpretation of information. “Canonical” means it embodies the rules that govern the information assets. These rules include descriptions of how the domains, sub-domains, entities and components associate with one another, hierarchically and otherwise, and where to go to find the systems of record that bring these entities to life, and the sources of truth that bring them together.
