1. Model Overview and Architecture:

In most applications, developers must design code and test every screen. This can be very time consuming and lead to inconsistency across an application in terms of look and feel, as well as functionality. 

Vienna Advantage simplifies the task by using a more advanced concept of a central active data dictionary. Windows are generated at runtime from the data dictionary. Developers simply define the rules for how the window displays and in what conditions.
