Introduction
This report is an addendum to the work formerly done as Inspection Phase in Assignment 1. Further, in
Assignment 1 we had chosen a Case Study that was Collins Car Parking System and overall Inspection
was done previously. In this report, we are going to Elaborate the work done in Assignment 1. This
report will further help Collin’s by improving those features that were not properly identified or poorly
identified.
To Elaborate the City Administration about the project this report will work upon finding main
Functional and Non-Functional Requirements for the major areas of the project. All the requirements
will be studied and a list is maintained for each requirement by critical analysis. After that Use Case
Diagram is made for the system for the better implementation and process flow identification. It will be
followed by Class Diagram that will help in identification of the real-life objects that are present in the
system. Both of these UML Diagrams are explained for viable Implementation. These diagrams will be
based on the assumptions that are espoused from the Assignment 1. SDLC for this task is also designed
and listed briefly on various design activities that will explain various task and phases for the Collin Car
Parking System (Faheem, Mahmud, Khan, Rahman & Zafar, 2013).

Requirement Identification
Functional Requirements:
Data Network
 The Collin Car Parking System must transmit data to the UI of the subsystem monitoring system
after every 30 seconds.

Monitoring System installed in the parking space.
 The Collin Car Parking System must be able to send a regular update to the customer those who
park car here.
 The Collin Car Parking System must be able to collect Parking information and should be able to
store it efficiently in the system database for every parking space used or unused in the building
at an interval of 30 seconds for at least a year.
 The Collin Car Parking System should be able to transfer data to any external device from the
Data Network.
 The Collin Car Parking System must print and display the record stored on the network.
 The Collin Car Parking System should be able to provide proper security for the Data Network to
maintain the integrity of the overall system.

them space availability.
Monitoring of Parking Space
 The Collin Car Parking System should detect if all of the parking spaces are occupied and send
this report to the external participants.
 The Collin Car Parking System should detect if any parking space within the parking area is
unoccupied and send this report to the external participants.
 The Collin Car Parking System Should detect if parking space loading zones and fire lanes are
occupied and send this report to the external participants.
User Interface
 The Collin Car Parking System should provide all the customers with the best criteria
mechanism for electing out parking space.
 The Collin Car Parking System should display receipts.
 The Collin Car Parking System should display the plan used by the customer.
 The Collin Car Parking System should provide an accessible source by which the customer does
not have to leave the automobile.
 The Collin Car Parking System should provide customer to get the on-demand parking space
information.
 The Collin Car Parking System should provide monitoring abilities to the operator for
determining the overall state of the parking state including at present parking space.

 The Collin Car Parking System should provide flag parking option to the on-duty operator using
which the unavailable spaces that are falsely displayed as available are flag as occupied.
 The Collin Car Parking System should be able to print receipts for the customer including Daily,
Weekly, Monthly, Quarterly and Annual charges with parking space usage.
 The Collin Car Parking System should be able to provide an output that could be customized by
the operator.

System Design
For this phase, the model that is chosen is Waterfall model that will help in developing the Collin Car
Parking System (Zhdanov, Korolev & Utemov, 2010). The Life Cycle used in the development is briefly
described below:
Describing the Environment
The idea behind developing the Car parking system is to provide an efficient method to save the car
parking space. This implementation model will help in making a reliable system that could be used by
various Customers in order to store their vehicles without the hassle (Wang, Song, Zhang & Deng, 2014).
Key Features provided by the New Collin Car Parking system
 Customer can reserve parking space for a minimal amount
 The newly designed system will be reliable and efficient to manage the parking spaces
 All the history of any customer can be viewed easily
 System will be able to work 24x7
 Regular maintenance would be implemented that will work very fast to reduce the off time of
the system
 Data Collection with efficiency in such a way that error in price calculation and parking Space
management is minimal
Environmental Requirement for the Implemented system
 The system preference is the Linux for secure access
 Sensors are implemented at every parking space that will tell whether the Space is available or
not
 At entry, the Car is scanned for threats
 The Car Numberplate would be recognized and liked to the Customer account
 Different APIs are used in order to Broadcast data over the network
 The Operator can turn off the System in case of any hazard
 Local Security measures are implemented for each and every Monitoring Stations
 The System used many protocols that enables the customer to interact with the system
efficiently
 Customer will be provided with an encrypted receipt for their Car
Hardware Requirements of the New Collin Car Parking System
 Automated Gates that open or closes when the car come
 Switches for each and every Monitoring Stations
 Network Cables to provide an interconnection between each Monitoring station and the server
 Networking Devices like scanner or sensors are used
 LED for the stop and go sign

 Card Scanning Devices for scanning the card of those customers that have reserved Parking
Space
 Barcode reader to read the Customer Receipts
 Devices that use Wireless connection
 For processing Back-end server a Dedicated Server is used
 Machine to generate Receipts for each customer
Software Requirements of the New Collin Car Parking System
 MATLAB that will help in creating a system code to process the digital images like number plates
of the vehicles
 Customer Database is stored on the cloud-based server for securing it from the hazards
 Antivirus programs to secure the Monitoring systems from the malicious hazards
 Payment calculation modules
 Payment authentication API
 Firewall to protect the Network from unauthorized access
Designing of Application Components
After critically examining all the Environmental Activities this phase will help in designing the application
and the components related to it. It is done by creating Application Boundaries and by describing each
and every functioning component of the Application Machine (Innovative Architects, 2018).
This is done with the help of the Use Case Diagram and tested with the tested feasibility of the system.
Use case Actor Domain Class Events
Park car Customer parkingInfo User can park the car
Search Parking Space Operator and
Customer
parkingInfo Search for available
parking space
Parking Allocation Operator and

system
Figure 4: Brief description of the System environment
There are several other features involved like to which Class the Use Case is Linked that will help in
getting insight into the machine work and the way it is going to process that job.

User Interface
When the Application components are determined properly designing phase will be implemented that
will include designing of an Interface. The Interface will be designed by keeping in mind that any less
knowledgeable person can use it. The user interface will clearly include the features and an easily
accessible module to implement the system. The User Interface will include Login Logout button,
Reserved Parking Space, Receipt collection, Payment module and many other features that will help in
better Usability of the System
Database and the Implementation Schema
After User Interface development, actual development of the system starts because of this the system
design should be designed very carefully. The system development team for Collin that will develop Car
Parking System needs to do something very wisely and precisely like:
 Choosing the Programming Language
 Back-End Processing
 Database system and server for storage
 Syncing of all Monitoring Systems
This will help in creating a system that would be easy to use yet integrated. The database used in the
implementation phase provides the developers to maintain the storage of the system and developing
the system in the real-time could cause many issues like compatibility and storage. A NoSQL database
can be used to store and work on the system like Apache HBase, Apache Hadoop or Amazon DynamoDB.
Software Methods
Collin Car Parking System needs certain software methods for the implementation of the system.
Parking system needs not to be dependent on the other environmental feature that helps in better
implementation of the system using all the variable like a database, a user interface to give a better
feeling to the customer.
Collin Car Parking System uses the following:
 Linux Operating System
 Database application
 Visa Plus
 Encryption Program
 Sensors

Conclusion
This assignment was the addendum to the assignment 1 work that was done previously. In this Case
Study One is Elaborated over various methodologies that could help in developing the system software
in a better and reliable way. This report has various design models that will help in making software for
the Collin Car Parking System.
In this report, fully functional and non-functional requirements of the system are critically analysed and
used to develop the system. The Use Case and Class Diagram are also made that is going to help in
making dedicated system for the car parking. This report also includes the SDLC model according to the
requirements of the user.
