it seems like Stephen and I are trying to sell you its own solution ;)
I like the Embedded Control solution very much... indeed I was working with that and it's very very powerful
though...
It's far more difficult to implement than the webservice behavior... If you have VS.Net you cerate an WebService app with one webmethod

[WebMethod()]
public void UpdateData(string data)
{
    // connection to db
    // update
}

in the client side you just have to copy paste someone's code to get the base line. Then you change the url to point the ws (.asmx) and voila!

anyway, if you need to do it fast go for the webservice behavior
