Okay, I have a client saying "but, really, what are the advantages of SQL Server over Access?".

I've tried to explain, but really she feels that something she can see would be better and easier for her (also better for showing to investors).

So, I was wondering if anyone knew of pages or sites that had tests or whatnot of Acess vs SQL server in terms of speed, concurrent connections, etc.

btw, please don't plug MySQL, thanx
