Generic design of the personalized service
The service is broken down into three subsystems (manipulation of user
preferences, itinerary searches and access to PerSyst; see Figure 3.10). Each
subsystem corresponds to a grouping of modeling elements providing the same
behavior unit. For example, the “access to PerSyst” subsystem contains the
PersonalizeSystem
class.

Design of the personalized service
The service being a Web application, we have used the UML extensions put
forward by [CON 00] for conceptual modeling of the service.
Figure 3.11 presents the diagrams of conceptual classes for personalized
itinerary search (without the classes for handling of the user profile, nor those for
authentication of the user).
