Hey there!
I'm a well certified M$ Professional (because it makes me money) and I'm working on almost entirely Linux now, after touching linux for the first time in September..
Anyways... If you like your M$ Access Database... You can use CrossoverXOffice (
www.codeweavers.com) and Install Office...
Of course if you are opposed to using a Windows emulator with Linux (as I am) You cou could do it web based..
I've been a website developer for about 5 years now and I use a lot ColdFusion programming... when developing under Windows, I always used Access as my backend databases... now moving to Linux.. I made myself learn MySQL.. which is very fast as I'm sure you know... Hasn't beena great deal of a change for me as I do most of my Database manipulation with ColdFusion anyways...
I haven't taken the time to learn PHP.. though I should because it's free... and ColdFusion server... well... let's just say it's not so free... But it's pretty easy to learn... and capable of just about eberything you could possibly want to do with a web-based server... even generating dynamic graphs and charts...
I hope this has helped....
