Notes

The WWS.NET system consists of multiple different applications running in a single application container (the plugin application) adapted to the needs of the different user groups. Every application implements a specific group of aspects of the WWS system. To enforce a consistent user experience and to provide only a single Windows application to the users, the system uses the plugin pattern. This concept is described in more detail in the chapter 3.1.1.
The different applications plugged into the plugin application are all structured according to a strict layer architecture, i.e. the layer architecture is the top level structural decomposition used. This layer structure is described in more detail in the chapter 1.1

All applications are built as plugins running inside the plugin application
Every application is structured into the following layers:

The layering is strict, i.e. it’s not allowed to skip a layer. The only exceptions are the common technical components, which can be used by interface, business and data access layer. Below the layer name, the diagram also shows the main frameworks / tools used in the corresponding layer, e.g. the Data Access layer is built based on NHibernate. The following chapters will provide more details on the different layers.
The logical layers are deployed as a rich client, i.e. Interface, Business and Data Access layer are running on one machine as a single application. The database is running on a separate server, i.e. it is a 2-tier physical deployment.
