Thanks!. Yes, I should add one-to-many. The idea is to have, in property types, "String", "Text", "Number", and "Reference to Employee", "Reference to Supplier", and "List of Photos", "List of Notes". The next idea is: add tags to each entity. You could add "urgent", or "author:johnny" to any entity. And make collections, that is, all the Notes tagged with "urgent". Another idea: generate code for the dynamic application. Or have a mobile client. Sky is the limit ;-)
