Part 1. Use Case Realisation for the ‘Record New Tour’ Use Case
Class Diagram
a) Class Diagram is commonly known as static diagrams that represents static view in an
application. For an information system, class diagram is used for visualizing, documenting
various aspects, describing the system, as well as constructing some executable code for the
application that is to be implemented. The attributes and the operations of a particular class are
explained in a class diagram. Main use of class diagram in a system analysis is designing a static
view of the application. It is also used for describing the responsibilities of a system and is
considered as the base of the component as well as deployment of the diagrams.

c) The above class diagram shows three class for the Record New Tour Use case. The
classes shown in the above diagram is clerical assistants, passenger, and tour leader. Clerical
assistants has attributes and operations defined in the class diagram. There are four attributes that
are included in the clerical assistant class along with six operations. The passenger class has four
attributes and three operations, which defines the passenger class. The Tour Leader class has four
attributes and three operations that are to be included in the class. The operations that the users
will perform are shown clearly in the class diagram. The classes are associated with each other.

3SYSTEM ANALYSIS AND DESIGN
The passenger class is associated with clerical assistant class and Tour Leader class. The clerical
assistant maintains all the tour records, drivers, hotels, customer enquiries, payments, invoices,
as well as provides catering establishments. The tour leaders are responsible for planning the
aspects of the tours. There are private variable as well as public variable attributes that are
present in the classes.
Communication Diagram
a) Communication diagram is used for showing the interaction between the users in a
system. It is an interaction diagram that shows about interaction of the objects. Communication
diagram is extension of the object diagram, which shows all objects with messages that travels
from one place to another. The purpose of using communication diagram drawing model
message that passes between the objects or the roles for delivering functionalities of the use
cases and the operations involved. Communication diagram is also used as model mechanism as
the architectural design within the system and also shows the capturing interactions showing the
passes of the messages in between the objects and the roles in the scenario.
