Part 1: Use Case Realisation for the ‘Record New Tour’ Use Case
1.1 Analysis Class Diagram:
The class diagram is the static structural model of unified modelling language. The
class diagram can be described as the collection of basic elements of an application. The
classes illustrates the data and functional requirements of every unit of the application. The
relationship in a class diagram shows the internal communication of application.
The class diagram provides the basic building blocks for the object oriented methods
and it can be considered the most beneficial feature of class diagram. The best way to capture
the structural pattern of an object oriented application is through the class diagram.

3SYSTEM ANALYSIS AND DESIGN
The class diagram in figure 1 has three classes. As per the description provided in the
record new tour use case, three classes are enough to meet the application requirement. The
class diagram shows that the clerical_class and tour_class are connected through an
association relationship. It is not mentioned in the class diagram how the clerical assistant
methods will be validated or how the assistant can access the system. The class diagram only
concentrated on representing the structural pattern of record new tour use case. Based on the
attributes and operations declared in the figure 1, other unified modelling language diagrams
will be created. The tour class is consisted of only the driver. Therefore, the driver_class and
tour_class has composition relationship among them.
1.2 Communication Diagram:
Communication diagram is also known as the collaboration diagram that shows the
interaction among the objects of the class. The connection between the objects are called the
lifelines. Communication diagram is similar to the sequence diagram and it is a part of
interaction diagram. Communication diagram does not show the structuring mechanism of
the application and life-line of the messages.
Like every other behavioural UML model, the communication diagram shows how
the system will response to requests of users. The communication diagram fills the gap of
class diagram by showing the order of the messages.
