Part 1:
Analysis Class Diagram
a) Analysis of Class Diagram: In a particular application, the diagram which shows the
static view of the application is commonly termed as class diagram. Class diagram in
information system is basically used for documenting different type of aspects, constructing
codes that are executable, virtualizing, as well as is used for describing application system that
are to be designed. In a class diagram, there are many classes that describes the activities along
with their operations that are going to be performed by the application. Class diagram are used in
many cases but the main use of class diagram for analyzing a system is making a static view of
that particular application that is to be designed. Class diagram is also used to describe the
system responsibility as well as can be considered as the basic component of diagrams and base
of deploying a diagram.

c) From the diagram above, it can be seen that the class diagram of the new information
system of RecordNew Tour has three different class that is designed for the system. The classes
that are described above shows consists of clerical assistants, the tour leader, as well as the
passengers who are involved mainly in the system. All the classes have different attributes as
well as operation that are to be performed within the class. The attributes that are involved in the
clerical assistant class are the attributes that are needed to define the clerical assistants of the
system. There are six operations that the clerical assistant needs to perform in the application.

3SYSTEM ANALYSIS AND DESIGN
The class of passenger has four attributes as well as three operations that are designed in the
class. There are total of four attributes in the class of Tour leader and this class will have three
operations that is to be performed in the class. There is an association between all the classes in
the diagram shown above. There is an association between the passenger class and the clerical
assistant class and there is also an association with the passenger class and the Tour leader class.
All the classes have public variable as well as private variable. The members cannot access the
variable that are private. All can access the variable that are public.
Communication Diagram
a) The main purpose of communication diagram is to show the main interaction between
all the users in a particular system. Communication diagram is commonly known as interaction
diagram that shows the interaction in between the objects. Communication diagram is mainly
done by extending the object diagram that shows all the objects with some messages for
traveling from one place to another place. The main motive of using the communication diagram
is drawing a message model, which passes between object or between the roles that delivers
functionalities used in the use cases as well as operations that are involved. Communication
diagram is commonly known as model mechanism.
