Analysis model
Items Models Purpose Representation
Object model Specifying properties and relationship of individual concepts that are manipulated by the system. (???????????) Class diagrams
Dynamic model Representing the behaviors and interactions among a set of objects. (????????????) Sequence diagrams

Object model

• The object model consists of
• Entity objects
• Representing the persistent information tracked
  by the system.
• (??????????)
• Boundary objects
• Representing the system interface with the
  actors.
• (???????????)
• Control objects
• Control objects are responsible for coordinating
  boundary and entity objects. (entity object
  ?boundary object ???object)
• Modeling interactions among objects with class
  diagrams. (class diagram ???object??????)

Dynamic model

• Sequence diagrams represent the interactions
  among a set of objects from object model during a
  single use case.
• (?????????(??????) )

Heuristics for identifying entity objects

• Terms that developers or users need to clarify in
  order to understand the use case.(?????use case)
• Recurring nouns in the use case.(????)
• Real-world entities that the system needs to
  track.(??????)
• Real-world activities that the system needs to
  track.(??????/??)
• Data sources or sinks.(??)
• Recurring Adjective in the use case , it is
  Attribute of object(??)

Heuristics for identifying boundary objects

• Identity user interface controls that the user
  needs to initiate the use case. (user?????use
  case)
• Identity forms the user needs to enter data into
  the system. (??????????)
• Identity notices and message the system uses to
  respond to the user. (user ???????)

13
14
Heuristics for identifying control objects

• Identity one control object per use case.
• (?use case ?????control object)
• Identity one control object per actor in the use
  case.
• (?actor ?????control object)

14
15
Heuristics for drawing sequence diagrams

• The first column should correspond to the actor
  who initiated the use case.(????actor)
• The second column should be a boundary object
  (that the actor used to initiate the use
  case).(????boundary object)
• The third column should be the control object
  that manages the rest of the use
  case.(????control object)
• Control objects are created by boundary objects
  initiating use cases. (control object
  ??boundary???)
• Boundary objects are accessed by control objects.
  (boundary object ???control object)
• Entity objects are accessed by control and
  boundary objects. (entity object ??control object
  ?boundary object??)
