Nine Kinds of Diagrams

• Structural
• Class
• Object
• Component Deployment
• Behavioral
• Use case
• Sequence
• Activity
• Collaboration
• Statechart

• Model Management
• Packages
• Subsystems
• Models

user could be broadly interpreted to include

Note it may be easier to define the classes in
parallel with defining the activities!

State Chart
16
Driver State Chart
Move to p/d station
state here is quite different from, say, a
petri net or finite state automata modelhere
state indicates what some entity is doing the
arcs primarily are signs to indicate the
transition from one kind of activity to
another So its important to identify all the
active entities, all their states
(activities) and what causes or indicates their
transition between activities

Some Observations

• UML does give us
• Structure classes and objects
• Behavior use cases, activity, sequence, state
  chart
• The rest is largely implementation oriented
• UML does NOT give us the precise methods for
  making decisions, or even the precise ways for
  performing a physical activity

Questions

• Are there good (free) tools for developing the
  use cases, class, object, activity, and state
  charts?
• Should these be part of the IE/OR toolkit?
