 //TODO Pruefe Architekturbeschreibung FE

+This component implements the presentation logic for the standby-planning-module using the Angular framework. The Frontend is a so called *Single Page Application* (SPA) because it behaves like a single HTML-page. The name of the war file is *spfe*.
 
-It divides the GridMeasureFE into three layers:
+Technical the frontend consists of the following building blocks:
 
-. *Components* - The components (Pages, Lists, Dialogs, Common Comp.) represent the presentation layer and the control layer. A component contains the control logic (.ts-file), an HTML-fragment as presentation description (.html-file) and a style definition (.css-file).
-. *Services* - The service component communicates with the interfaces of the backend via HTTP requests by using the model component.
-. *Model* - The model corresponds to the View-Model of the backend tier.
+
+. *Modules* - There is one Core Module which holds all the singleton assets of the application like login, authentication service, navbar,etc. The Shared Module keeps all the reuseable elements like general components, directives, etc. In addition to these two Modules there are several Feature Module which encapsulate one functional requirement each like masterdata-management, standby-planning or reports.
+
+. *Services* - Each Module has itś own Services which are mostly used to make restcalls to the backends.
+
+. *Components* - In each Module you will find a component section which holds the different Components.
