Thank you, but i already know about mysql, ive used it in a few projects in the past. It works ok, but it uses a bit high amount of resources (around 40-50mbyte of VM and another 10-20 mb of PM on my winxp, not tested under win98)

Is there any other alternative that uses less resources?

edit: i forgot to say that i have to run the server locally, theres no any network connections available!
