Analysis Class Diagram
Analysis class diagrams are defined as the graphical representations with a static structure
and these are created with a motive to bring out the information system structure along with
the interaction between the different system components. The diagram comprises of the
system classes, attributes, and the dependencies. The specific details of the information
system can be obtained by studying the analysis class diagram. System development teams
can gain a lot from these diagrams as specific details of system behaviour, system interaction,
and relationships can be acquired to develop the system accordingly. Also, the requirements
are included as per the knowledge gained from the diagram.
Decisions made during analysis class diagram
There are primarily two categories of staff that are involved in the Record New Tour use
case. However, these have not been illustrated in the class diagram depicted above. The main
reason involved in it is the specific attributes that would have illustrated the same were not
available. For instance, two different types of users, such as an administrative worker and the
tour leader could access the details of the tour and differentiation between them would not
have been easy. In the same way, the tours may be of two categories as day trips or extended
