Analysis class diagram
In any information system the classes represent the entities with a level of an abstraction
along with some characteristics. The associations among the different classes denotes the
relationship among the classes inside the system. along with this, the class diagrams are also
helpful in depicting the overview of the proposed information system to be built while describing
objects and their related classes inside it. Following is the class diagram for the use case;
Furthermore, it also has wide range of usage, which includes the modeling of domain-
specific data structures in order to have a detailed design view about the system (Shen, Tan and
Siau 2018). With the help of the sharing models it is possible for the analysts to reuse class
model in interaction diagrams in order to model detailed design about the dynamic behavior in
different scenarios. Moreover, the class diagrams are helpful in exploring the related data and
attributes of the classes, getting faster realization of the entities which will be important in
developing the system. In addition to that, analysts can also notice whether there are too

few/many classes for the proposed system and relationships between the objects of those classes.
Too complex or too many relationships can increase the dependencies among the classes/objects.
Communication diagram
Communication Diagram are mainly used in order to model and depict dynamic behavior
of a selected use case for the proposed information system for wide world tour. When the
communication diagram is compared with the sequence diagrams, it is found that communication
diagrams are more concerned in depicting the collaboration between the objects instead of time
sequence of the interaction. Following is the communication diagram for the Add tour Use case;
It is also possible to automate the creation of both the diagrams manually because CASE
tools can generate from one to the other (Srinivasan, Lee and Yang, 2016). Through the
communication Diagram combination of the information collected from use case, class diagrams
as well as from the sequence diagrams that describes static as well as dynamic behavior of the
proposed for Wide World Tour Management System. Through the communication diagram it is
possible to model alternative scenarios for a chosen use cases that requires involvement and
