1. I understand we cannot put FKs as a listed attribute on the ER diagram/attribute dictionary, but what if this FK would be a part of a PK? Is it okay to not have an attribute identified as the PK or do we have to find some other PK? 2. In the occerence column in the data dictionaries, is it advised to have a specific example or to use entity names? So far I have been using entity names e.g., 'vehicle resides in depot', but I feel a more specific example e.g., 'ford focus resides in depot 01' is clearer to the reader. 3. Should we include an alias that is the same as the entity name if there are no aliases? Or just leave it blank? Apologies if any of these have already been answered in the forums, I couldn't seem to find any answers on these.
