The first two chapters of this book focused on the basic modeling principles of relationships and how to import data into the model. This chapter extends those concepts by focusing on the development of the end-user experience. That is, how the user interacts with the model and the experience they have when doing so.
This chapter also examines a fundamental decision that the designer should make when designing the model, that is, the use of role playing dimensions. The choices available through role playing dimensions should be considered by the modeler as part of the initial design.
