AH Naming Standards
Views
View names start with the Activity Hub that sources the majority of the data in that view. The name of the view is based on the lowest level of detail contained in that view.
Fields
Field names are largely sources from the AH Steering Committee. Field names are designed to be as clear and intuitive as possible. Fields definitions are added to the Information Governance Catalog (IGC) as they are defined.
