Hi, I'm a Revolution user new to Valentina. I want to build and serve a Runrev app with Valentina as my db. I'll be serving it on our mac server to <5 people. I'm unsure as to what I need VDN, Valentina Office ?? I have Valentina 2 ADK. I don't quite get how the client Runrev apps link to the RunRev/ Valentia database. thanks for any help chris
