UI Methods and ArchitectureArchitectureETP Architecture

This section describes the use of Entity, Task, and Presenter (ETP) classification as an architectural organizing principal. This classification is an elaboration of Jacobson's entity, control, and boundary classification. ETP extends Jacobson's control classifiers to encompass not only flow of control in application logic but also the flow of activity in organizations (process) and individual work (user tasks) extended down to the application's interface (what user goal is satisified by a particular "control" classifier).

For a broad overview of this approach, see Artim's chapter, Entity, Task, and Presenter Classification in User Interface Architecture: An Approach to Organizing HCI Practice (included in Object Modeling and User Interface Design—Designing Interactive Systems, edited by Mark van Harmelen, Addison-Wesley Object Technology series, ©2001).
