Analysis Class Diagram
a) Class Diagram Definition
Class diagram is a part of unified modelling languages which offers a structure and
overview of a system methods, attributes and classes. The diagram also defines the set the
relationship among different classes. Computer aided software engineering is considered
as a domain of software tools which is mainly utilized to implement and design
application in different areas. It is very much similar as CAD which stands for computer
aided design. It is also utilized to show the functions of the system servers and classes.
Every classes has also mainly two aspects as attributes and functions. In order to provide
a conceptual architecture and model of a primarily design, it is highly recommended to
develop class diagram. Basically, a class diagram consist of several classes along with its
attributes and functions of a system.

c) Summary
The above diagram shows the classes of the TMS system. In this diagram three classes are
identified as Clerical assistant, tour leaders along with branch manager and tour. These are
the main three actors responsible for record a tour. The initiation process can be start by both
clerical assistant and branch manager as they both could add tour and other tour details. The
clerical assistant has several attributes as clerical assistant name, clerical assistant ID, clerical
assistant address. Additionally, the class has several functions like add driver code, add tour
description, add tour leader, add tour location, update tour leader, Check customer payment
details, record payment details, record venue invoices, update record details and update tour
location. The clerical assistant class forms one to many relation with the class tour which also
has one to one relation with the tour leads. The branch class has a one to many relation with
the tour class well.
Communication diagram:
a) Definition
Communication diagram shows the interaction between different objects. Commonly it is
considered as an extension of object diagram which shows message with appropriate
direction from one object to another. It has been helping in the developemnt of the system in
appositive manner that [provide high efficiency rate to the output. It also model alternative
scenarios within the operations that associates with different collaboration of different
objects. It also support the identification of objects, and their attributes and operations that
participate in use cases.
