Hi,

I am currently designing an industry-specific app that I would like to sell to multiple clients.

I was thinking of creating a single app (or DB) that has all vendors in it and uses it between all clients. This way I didn't have to populate each deployed app, for each client, with all the same information.  In addition, if there are changes, i could make the changes in 1 place, and all client app would get the update. 

Main DB (Vendors) -->    Client App1

                                          Client App2
