The critical data modeling issue is learning to think like a data modeler. The representation method is a less important concern, because all dialects of these methods capture the same core data. For data modeling teachers, there are two issues. First, what representation method enables quick sketching of models on a board? Second, what method should students use to capture the fine detail for their assignments? Other issues related to teaching data modeling are also discussed, including the argument for intertwining the teaching of data modeling and SQL.
