Introduction
The process which comprises of work activities and organisational settings that are being
assisted through new information system for either expanding either existing or modifying it is
referred to as information system development. Data modelling refers to process that is related
with creating data models for storing data within them (Awasthi and Omrani, 2019). The steps
which are being used for formations, formulate plans along with controlling process for
developing information system for having computerised methods is defined as system
development approach. There exist wide range of concepts which are being utilised for
development of system; they are users, system testing, interface, maintenance, deployment, etc.
For understanding this conception, Kangaroo Taxi is taken who have started rendering their
online taxi services around Australia. This report comprises of distinct diagrams for furnishing
adequate information related with system of organisation.
Outline of case study
Kangaroo Taxi is delivering services in Australia for their users by providing them with
online taxi services. For this, they have developed their website that can be accessed by
registering in it through usage of mobile devices. Users need to login into the system by making
use of their credentials like username, contact number, address and other details which are being
asked. This has to be done only one time as at next time users need to directly enter their
username as well as password for having essential details related with services they need to have.
Here, user can check all the essential details related with taxis, fares to different destination as
well as they have option to choose the payment method as per their convenience. For the
security of passengers all the essential details of their drivers are being given when they have
made bookings.
Use case Diagram
The primary form of software or system needs for new software programs which are
underdeveloped is referred to as UML case diagram. They are liable for specifying anticipated
behaviour and it will not furnish actual method with respect to how it is being done or happening
(De Rooij, Mannak and Janowicz-Panjaitan, 2019). They are being specified either in textual or
visual form. Basically, it will aid Kangaroo Taxi to design a system from perspectives of their
end users. This denotes effectual technique to interact with users in terms of visualising the

external system behaviour. Generally, it is a graphical depiction which is liable for interacting
with distinct entities within the system. It will be used for identification, clarification along with
organisation of system requirements. In this context, system implies something which is being
developed and operated such as sending emails related with offers given to their customers for
captivating them so that they opt for services that are being furnished by Kangaroo Taxi. UML
denotes standard notation to model objects within system. In context of Kangaroo Taxi, the
different use case is depicted beneath:
Illustration 1: Case diagram for User registration
The registration process is being depicted above which can be used by users when they
need services from Kangaroo Taxi. When customers will enter into the website for the first time
then they have to register into the system. This is being done so that firm can authenticate their
users and also provide ease to them when it is being utilised next time. Here, users will enter
their name, contact number address and email id. All these details will be authenticated by admin
and will create an account for them. The next time when users will enter into the system they can
login by making use of system generated username and password.
