The value of a Web Service is its ability to isolate the program logic from the interface. To get a feel for what can (or should) be done with a Web Service, remove all references to your Database from the Web Application and begin writing Web Service methods to replace them.

Once you've done this, try developing a new interface (application) on a different platform - like Pocket PC, Windows Forms or VFP. While you are developing the new interface, you will be forced to re-factor some of the Web Service to make it more generic so it can handle multiple interface platforms.

This will give you an excellent view of what a Web Service can do.
