Putting an app on a LAN... nothing really... it just loads over the network instead of from their local hard drive. If it's a big app or requires a lot of DLL's, it could take a little time to start up, but once it's loaded, there's no difference.

Or... are you asking about creating multi-user database applciations?

That, I suppose would play a role. Is there a big difference in single-user versus multi-user DB's

Is there a big difference? Well, yes and no... it's never easy right!

Most databases, these days, are multi-user anyway. Some more then others. Like MS Access is a multi-user database, but not really an RDBMS in that it's not a database engine on the network responding to requests but a flat file system.

The biggest issue is making sure that the database design and application design provide for maximum concurrency. You don't want to have to update (and therefore lock / block) hundreds of rows at a time which will prevent others from updating concurrently.

Any more specific questions?
