Access vs. MySQL

Its like comparing apples with oranges!!

Both are relational databases.
MySQL is free Access is NOT
Access is more than a database it is also a development tool for making applications (Forms reports etc.) that is NOT possible in MySQL.
Access does have its limitations as a multiuser database I think we are talking about 255 (theoretical)connections at the same time. It si much more in MySQL.

So if you want a database which is free and its going to be used on the WEB then MySQL is you rbest bet. If you want a very good database to quickly make finished multi user applications then Access is the best, but ist going to cost you.
