Hello there.  Lets suppose that I have Nop and Umbraco installed on the same server.  I don't really combine them in any specific way, I just have both tools sitting there on the server.  If a user logs in to one or the other (a user could be a general user or a admin, general users can't log into Umbraco admins can log into either) how would the two databases need to interact?  What tables and so forth would have to be accessed, updated and so forth?


Thanks for your imput.
