Part 1:
Analysis Class Diagram
a) Analysis of Class Diagram: Class diagram is basically considered as a type of diagram
and is also considered as the part of the UML (Unified Modelling Language) Languages. Class
diagram defines the structure of the system and provides the user and the reader the structure of
the system that defines the classes, operations or methods that the class will perform in the
system and their related attributes (Turco, Pietro and Martignano 2018). Class diagram also
offers relationships between various classes. The class diagram also illustrates functional
diagram of the system that is being designed and serve the developer as development resource in
the software development life cycle. Class diagram provides conceptual diagram to the
developers.

c) Class diagram is used by developers because this provides standard notation for the
software design. Class diagram is considered as the only design of software notation that are
most familiar. Class diagram that is shown in figure 1 shows the modelling elements as well as
the relations, which helps to specialize the domain or the technologies that are to be used by the
Record New Tour system. The above designed class diagram shows the conceptual model that is
proposed for the new information system of the business. The architecture of the new system is
developed using the class diagram. The architecture consists of three classes that will define the
use case of the system. All the classes shown above have attributes with the operations they will

perform in the new information system. The classes defined above are clerical assistant class,
tour leader class and the passenger class that have different operations in the new system. All the
classes are associated with each other.
Communication Diagram
a) Communication diagram is also known as collaboration diagram or an interaction
diagram that illustrates the relationship and the interaction in the software objects in a Unified
Modelling Diagram. Communication diagram states the communication that is to be in the
information system (Ptak 2018). The communication diagram is not a new concept to the
developers of the system analysis and design. This communication diagram defines all the
modelling paradigms that has already evolved (Vu et al. 2015). The interaction in between the
lifelines in the system are defined in a communication diagram that defines the architecture of
internal structure and the way communication diagram corresponds the message passing as the
central of system.
