In a multi data model environment, it could be useful have some centralized diagnostic functions for a quick control through all data models for some common controls, e.g.
1 Relationships (missing parent)
2 Relationship (missing child)
3 Entities saturation (e.g. that highlight all entities with saturation > 80%, or with capability to choose a threshold)
This function(s) should be available in panel sys \ administration
Running such functions all data models will be analyzed and it will be produced a report with data model / entity / type of error.
Also the impact analysis should be improved with some cross-functions. E.g. search an entity name through all data models, or if a data source is used in more than one data model...
