This recipe will introduce you to the real-world business mobile apps and their related application servers. It is not a simple world. It is full of well-known traps and full of specific traps related to your infrastructure, your business logic, your application transactions, and so on. Just to be clear, you have to take care of your design and the way you implement this design in a much more extent compared to a classic client/server application. On going deeper into the mobile programming (and in general, in all asynchronous scenarios), you will see that things become harder than usual. In the mobile world, things can get messy really fast and your customers will complain even faster. Be warned!
This recipe is a mobile client for the People Manager application server developed in the Implementing a RESTful interface using WebBroker recipe in Chapter 5, Putting Delphi on the Server.
