Using web service to update rows on InfoPath form

Question

I managed to get a proof of concept working where I can read data from a web service to populate a table on my InfoPath form. I have found information about how to use a web service to "submit" data from the InfoPath form. But what if I want to
update an existing record from the read that I displayed on the InfoPath form?
I have some simple methods in my web service for "read employees", "insert employee", and "update employee". Nothing really fancy. I think I can manage to tell InfoPath to use "insert employee" for the submit command,
but I'm not entirely sure how it knows exactly what to submit. I have no idea how to tell InfoPath to use the "update employee" method if a user edits a record, nor, what button to push to do that.
I have a feeling that "submit" is supposed to cover both "insert" and "update" but I can't find anything to confirm that. If that is true, I am not sure how to handle responses from multiple calls if the user tries to update
or add multiple rows at a time.
If "submit" does handle both "insert" and "update" then is best practice to make the web method intelligent enough to tell the difference?

Given that IP has been killed off by Microsoft, and that you are still in the dev process, I might not recommend its use. Consider BCS instead.
