@nipsuli if you don’t care about reuse or forward engineering, then Miro or any diagramming tool will do. If you want forward engineering and learn the best #datamodeling methodology around (FCO-IM), then use #CaseTalk. Other alternatives for logical models that can be turned into physical are SAP #PowerDesigner, #erwin and Idera ER/Studio. Check with @casetalk or @marcowobben on the first.
