Summary
In this chapter we have explored using Web services to integrate a PDA application with the enterprise. For PDAs with more limited memory and processing capacity, we have seen that Web services are possible, but a preferable technique is to use a proxy on the server. The proxy does as much of the work as possible on the PDA's behalf, and exchanges information with the PDA using a very simple protocol.
For more powerful PDAs, such as the PocketPC, we can use SOAP directly to access server-side functionality.
