After a short hiatus, Granville Miller re-opens the UML workbook for an in-depth discussion of one of the fundamental components of the use case diagram: the actor. The actor is not only essential in UML modeling, it can also play an important role in creating Java applications and may even suggest patterns in J2EE application design. The actor becomes especially important when it comes to developing complex systems such as Web services, where external interactions play an important role in the system design. Follow along as Granville uses sequence and class diagrams to explain the role of the actor in use case diagramming and Java application development.
