Systems Analysis and Design (IMAT5205) Assignment 2: Modelling Report

This report presents a comprehensive analysis of the 'Record New Tour' use case within the context of the Wide World Tour Management System, fulfilling the requirements of Systems Analysis and Design Assignment 2. The analysis includes a detailed examination of the system through various UML diagrams. The report begins with the Use Case Realisation, which involves an Analysis Class Diagram that illustrates the main classes, attributes, and associations within the system, such as TourLeaders, Tours, ClericalAssistant, and Driver. Following this, a Communication Diagram is used to depict the interactions between actors (primarily the clerical assistant) and system objects, illustrating the flow of messages. A Sequence Diagram is then constructed to visualize the order of interactions between system components, such as the clerical assistant, Tour, Drivers, and Tour Guides. The report concludes with an evaluation of the CASE tool, Enterprise Architecture, and its role in supporting system design, reducing development costs, and aiding system analysts in the software development process. The report also highlights the benefits of CASE tools such as checking syntactical correctness, supporting data dictionaries, ensuring consistency and completeness, and aiding in requirements tracing and report generation.

SYSTEM ANALYSIS AND DESIGN
Part 1. Use Case Realisation for the ‘Record New Tour’ Use Case
Analysis Class Diagram
a. The analysis class diagram is basically a representation of the concepts in the problem and
focuses directly on the concepts of the domain and not on the entities of the software. It
requires using the actors and the use case related to the actors in the system. The construction
of the diagram can be done at the same time as that of the development of the use case
diagrams in the system. The analysis class diagram is basically used for the illustration of the
concepts, the attributes in the concepts and the association in between the concepts.
b.
c. The above developed diagram has been used for the decomposition to the problem domain
into clarify able terminologies. The main classes identified in the diagram are the
TourLeaders, Tours, ClericalAssitant and Driver. The main entities of the Driver Class are
DriverCode, DriverName, PrefferdLocations, PrefferedTourType and Status of the driver

which is used for checking if the driver is available or not. In addition to this, the Tour
Details class used for the storing the details of the tour where two methods are included
which would add a details of a tour and the clerical assistance would be able to save the
details with the method. The other class in the system is the Driver whose details are stored in
the system. The status of the drivers can be checked in the system using the view drivers’
method and when a free driver is found the driver is assigned to the tour.
Communication Diagram
a. The communication diagram is used for extending the object diagram and helps in
displaying the messages that are sent from one point to the other from within the system. In
addition to this, the association within the objects in the communication diagrams the
messages that are exchanged in between the objects in the diagram are also displayed. This
type of diagram is also known as the collaboration diagram and acts as an interactive
illustration which is similar to the sequence diagrams but generally focuses on the
relationships in between the objects. The diagram displays the objects and also the
association in between them.

c. The communication of the Diagram for the Wide World Tour Management System has
been described above. The diagram has been used for the description of the interaction of the
actors with the objects in the system. The main actor identified in this system is the clerical
assistant. The clerical assistant interacts with the other objects in the system which are tour,
driver and tour guide details. The actor would be able to store new details in the tour class.
The details would be saved in the system using the save tour method. The driver class is used
for implementing the view details method and the assign details method. The driver id and
the other details about the drivers are also stored in the class. All the classes are directly
associated with the tour class that
Part 2. Sequence Diagram
a. The sequence diagram is used for depicting the interaction that takes place in between the
different objects that are used in the system. The flow of the messages is displayed in the
diagram that are used for the illustrating the flow of the process and communication that
takes place within the system. The order in the which the messages and the processes take
place in the system are also depicted efficiently by the sequence diagram. The sequence
diagram can also be categorized under the interactive diagrams; this helps in the visualization
of the business in front of the designer who would be developing the system. The developer
would be able to identify the objects and the actors who are acting in the system currently.

c. The sequence diagram has been constructed for the Wide World Tour Management System
for displaying the flow of messages in between the different components of the Wide World
Tour Management System. The main actor object in the diagram is the clerical assistant. The
objects in the system that the actor would be interacting are Tour, Drivers and Tour Guides.
The actor performs all the actions in the system such as adding the details to the tour and
saving the details of the tour in the system. After the tour has been added to the system the
driver list is viewed by the system and the available driver from the list of drivers are
allocated to the tour. The tour guide number is also entered into the system to link him up
with the tour.

Part 3. Evaluation
The CASE tool used in this report is the Enterprise Architecture and this tool has been
used for the description of the different type of functionalities in the system and the CASE
tool helps in the supporting the description of the system with the possible illustrations that
would be helpful for the designer of the system to visualize the system efficiently and
develop the system according to requirements which have been defined to them by the
illustrations.
CASE tools are known as the Computer Aided Software Engineering technologies
that would provide assistance to the software development for the Wide World Tour
Management System. The main aim for using the CASE tools for the system development is
that the tool would be reducing the cost and time for the development of the system to a huge
extent. The main interest in the development of the CASE tool and the environment followed
by it is that it is based on the requirements of the organization. The tool is very useful for the
system analyst or the system developer that would be developing the system and the CASE
tool is basically the computer-based support that would be used for the software development
process and it is helpful for the analyst to support the development of the system and it is also
used in the time of integration of the system. This procedure would also be helpful in
displaying the integrated system to the clients and also will be helpful for the analyst in a way
that it can be used for the sub dividing the system so that all the functions of the system can
be utilized for the system efficiently and the processes in the system would be able to
encompass the functionalities of the different aspects of the system very efficiently. A
number of feature is offered by the CASE Tools and the also the communities of the business
processes through the diagram support feature that is allocated to the business community
with the use of the tools.

SYSTEM ANALYSIS AND DESIGN
The CASE tool provides a number of features that would aid the system analysts and
these features are listed below:
 The syntactical correctness is checked by the system
 The support for the data dictionary of the system is also allowed by the CASE tool.
 The consistency and the completeness are defined by the system
 The layering of the system is also done with the help of the CASE tools.
 The CASE tools helps in the tracing the requirements for the system.
 The reports of the system are generated automatically by the CASE tools.
 The simulations of the problems are aided by the CASE tools.
 The analysis for the performances of the system is done with the help of the CASE
tool.
The tool helps in automating the system of the organization by using a step by step
methodology for the system and the software for the organization. It is also characterized by
the steps that are to be taken for the development of the software for the organization. The
different tools can also be used for integrating all the different parts of a single system as the
they would be helpful for the developers to develop the system and maintain all the steps
necessary for the development of the system. The system developers job requires the analysis
of the software and process the designs of the system. The data design and the programming
are among the activities that are aided by the tools. However, there can be a different set of
developers who are assigned with the different activities, where one of the designer is
dependent on the analysis and another on the design. There is various type of activities that
include the feasibility studies and the others would be able to concentrate on the other parts of
the system development. The maintenance process is also aided by the CASE tools and they
help the system analyst to develop a maintenance plan after the system was developed.

SYSTEM ANALYSIS AND DESIGN
The multiple level of layers of knowledge for helping the analyst in distributing the
knowledge about the system. The staffs who would handle the system would be able have a
self-learning ability and provides the developers in developing an improved system. The
knowledge is very helpful for reducing the complexities in the network which would useful
for the system development.
