Introduction
Information systems development is defined as a process in which work activities or
organisational settings are being facilitated by introduction of new information system for
modification or expansion of existent one. System development approaches are being referred to
steps which are being utilised for forming, planning as well as controlling processes for
development of information system for driving towards computerised methods (Awasthi and
Omrani, 2019). The process associated with creation of data models to store data within the
database is referred to as data modelling. There are wide concepts which are being used while
formulating a system, they are user and system interfaces, system testing, deployment,
maintenance and many other. T o understand this concept Kangaroo Taxi is into account which
is a new firm and have started delivering online taxi services around the country. This report
comprises of different use case diagrams, entity relationship diagram, class, sequence along with
activity diagrams to furnish adequate and in-depth knowledge about these aspects.
Overview of case study
Kangaroo Taxi has started delivering their services across Australia for their users. They
have opted to furnish online taxi services. They have made a website which can be accessed
through smart phones of users. Users have to make registration when they will use it for the first
time and enter essential details like name, contact number, etc. This has to be done only one time
and next time when user wants to have services they can directly login into the system by
making use of their credentials. The system will render them with estimated cost associated with
their trip. Along with this, users can check for available taxis, details of drivers and also make
online payments for the same. Basically, a system is designed by them to render as system to
their user to furnish them with ease while looking for travelling from one point to other.
Use case Diagram
The graphical illustration associated with interaction that takes place among distinct entities of
system is referred to as use case diagram. Generally, this implies a methodology that can be used
for determining, clarifying as well as organising system needs. System denotes something that is

being developed or operated like sending a mail associated with details related with trip
(Beratan, 2019). Here, unified modelling language is being utilised that implies standard notation
for modelling of objects along with systems. UML is a standardised modelling language that is
liable for enabling developers to furnish specifications, visualisations, construction along with
document artefacts related with software system. For an instance, with reference to Kangaroo
Taxi, the details of customers in terms of what they have to enter within the website will be
furnished in a visual manner. By this developer can have insight into if everything is alright like
all the essential details have been entered or some new fields or entities must be added. A clear
picture illustrates better understanding of entire systems which s being developed. This involves
justification of hardware designs, overall planning requirements, software debugging as well as
their testing in context of service oriented aspects of tasks (De Rooij, Mannak and Janowicz-
Panjaitan, 2019).
With reference to Kangaroo Taxi, the use case diagram has been illustrated below:

The diagram illustrates registration process which is being shown to user while they enter
into website of Kangaroo Taxi for the first time. Here, users have to enter details like their name,
