Now what about something like inserting a record? Some table could have beaucoup fields which would mean just as
many params.

Maybe create a client side data set, add the data to it, convert it to XML and pass that to the WS?

Or is there a better technique?

A few of our customers access some web services from other platforms and we wanted to be sure to maintain platform independence. That's why we return data as a string that's simply the XML representation of the data (MyDataSet.GetXml(), as I already mentioned).
