Figure 2 : Declaring Exceptions in the Teallach Task Model
This paper has presented an overview of the Teallach task model, and has described how, using model-based techniques, it can capture the often complex information processing requirements and human-computer interaction necessitated by user interfaces to object database applications. Through its tightly coupled domain and task models, Teallach can easily and transparently access domain knowledge and functionality provided by the underlying application. This allows Teallach to model more accurately the information processing requirements of an application user interface.
