Moreover, it allows for the creation of custom functionality that can be exposed through its client interface and subsequently bound as method bindings. Method bindings declaratively bind user interface components to back-end data and services providing data access.

Custom application module methods can easily be exposed as web services through the application module service interface. Moreover, application modules and their configured view object instances can be exposed...
