Could someone explain to be the workflow/possibilities of Sharepoint or other
Access services? Please forgive me, in advance, if I do not get all my
terminology right on this subject.

I continue to read things about Sharepoint and Access Services that hint at
what I would like to do, but I don't quite understand what they do or how
they intergrate into Acess or if they will for sure be a solution.

Do any of these services make it possible for users to access a database
from the the internet? If not is there a way to do this without building a
php or asp based website to access the data?

I understand that Access can connect to a mysql database, but can it connect
to one that is on a web server? Am I even asking the right questions?

Thanks.
