This document describes the architecture of a Silverlight application. It includes a client/UI module built with Silverlight and ASP.NET that communicates with web services. These web services provide access to data sources. The architecture also includes a framework with common components like business entities, data access, security services, and application modules. The framework is shared between the client/UI module and any server-side components.

We must implement anything related to Data Access as a server side solution
as well anything that performs complicated or very long elaborations (to keep high the
responsiveness of the application, remember we do not have blocking calls in Silverlight)
