should not be loosed during backup and migration for keeping all the details of the entries and
details of the users.
Performance – the output displayed to the customer should be accurate and the time
required for connecting with the database should be kept minimum such that the waiting time to
get the message is minimum. The support for the customer should increase with the increase in
the demand with the application of virtualization and cloud storage options that can be integrated
for increasing the scalability of the current information system.
Security – An authorization should be used for accessing the information system and the
details of the customer and the reservation details should not be accessed by the unauthorized
users for increasing the security the car parking information system. The footage generated from
the CCTV should be stored in local storage for monitoring the activity of the users of the car
parking system and use as an evidence for handling the emergency conditions.

OBJECT MODELLING
Use case 2 – Parking
When the user approaches to the entry barrier the camera reads the license plate and the
database is searched to find if the customer is a fixed customer. The fixed spot details are
displayed to the fixed customer and if the customer is not registered the empty spot details are
displayed and a spot is allocated to the user. If the license plate is not recognized the user is
provided the option to manually input their registration number and use the information system.
Use case 2 – manage Account
The details of the accounts can be updated by the user and for that the user need to
connect with the information by authentication with their old details.
Use Case 3 – View Reservation
The existing spots allocated to the fixed users can be changed by authenticating into the
user account and finding the free spots available in the system. The edit option is used as a sub
case.
Use Case 4 – Register
It is used by the unregistered users for registering with the current parking system. The
user needs to fill a registration form for registering with the information system
Use case 5 – manage parking
The current usage history, available wallet balance, parking prices can be viewed by the
user by connecting with the application and logging into the account.
Use case 6 – Edit reservation

For canceling the registration or editing the data and time of reservation the user needs to
edit the details 30 minutes before the actual time starts
Use case 7 – register vehicle
This is used for registering another vehicle with the account of the customer and the user
needs to fill a form and submit is for recording the details of the vehicle in the information
system.
Use case 8 – Edit vehicle details
The registered user can edit the details of their vehicle after authenticating into the
information system.
Use case 9 – Authenticate user
The accounts for the fixed customer are created and they needs to use their registered
email ID and password for logging into the system. The details are fetched from the database and
a new session is created for the user to maintaining the access to the information system.
Use case 10 – Set price
A tariff plan is followed and is displayed to the customer for choosing the best plan
according to the needs of the customer.

4. Specific task required for the design activity
4.1. Environment
For the development of the Collins car parking system and software development
environment should be created following the software development methodology such as Agile
or waterfall models. The main elements required for the creation of the environment is the
development of a communication plan for maintaining communication with the external systems.
A message format should be used and a set of communication protocol should be used for
communicating with the stakeholders associated with the development of the car parking system.

12
OBJECT MODELLING
Some security methodology should be applied for detection of the errors and maintain a recovery
mechanism for confirming the application of the new technology for the development of the
Collins parking car parking system.
4.2. Application Component
This are the elements that are used for defining a software program for performing some
specific function. The components consists of the scope and size of the functions, interfaces and
the boundaries of the system. The accepted programming language that can be used for the
configuration of the information system should also be analyzed for starting the development
process. The components and the additional that are required to be purchased in order to develop
the car parking system should be listed and integrated with each other during the development
process for reducing the errors in the final build information system.
4.3. User Interfaces
An user interface should be designed with the company’s logo and the it should be kept
same for the entry barrier and the mobile application designed for the Collins car parking system.
The user interface plays an important role for the productivity and the success of the network and
it is required to analyze the user requirement for designing the user interface for the system. All
the functionalities and options should be available to the user and the involvement of the user in
the development process can reduce the errors in the project. According to the current needs of
the system multiple user interface should be developed for different devices such that it can
fulfill the different needs of the customers using the car parking system.

4.4. Database
The database of the information system designed for collin’s car parking system should
be developed for storing the data generated from the activity of the users and provide the users
the result of their query. The use of relational database management system can be an ideal
choice for the organization and for this there is a requirement to convert the data model of the car
parking system into the relational database. The different issues generated during the
development of the data model should be addressed for reducing the errors in the database and
management of the throughput and the response time of the database. The security of the
database should be at the high level such that the data cannot be retrieved by any unauthorized
users and the information’s are kept secured.
4.5. Software Classes Methods
The software methodology for the development of the car parking system includes the
creation of design class diagrams, state machine diagrams and sequence diagrams. The Collins
car parking system is developed following the software development lifecycle methodology. The
different phases of the SDLC model should be followed for the development of an error free car
parking system. The five phases of the SDLC model are the planning, analysis, design,
implementation and maintenance.
The planning phase is used for the requirement analysis and different procedure such as
brainstorming with the development team and the using a set of questionnaires for interviewing
the stakeholders can be used. It is important to create an initial project plan and analyze the
resource required for the development of the project.

14
OBJECT MODELLING
The analysis phase is used for the identification of the cost and the hardware required for
the development of the information system. The errors generated in the system should be
identified and it should be removed for the development of the project. The codes and programs
used for the configuration of the devices installed in the network of the car parking system
should be checked before deployment and the errors in the codes should be identified such that
the car parking system is fully functional and no errors should be generated during the day to day
activity.
A preliminary design of the car parking system should be developed for the installation of
the sensors, entry and exit barrier and the servers for connecting with each other. The creation of
a dmz zone helps in securing the servers from physical access and secure the information
residing in the servers. The hardware and software required for the development of the
information system should be identified for the creation of the design of the car parking system.
The design plan should be followed in the implementation phase and servers and the
elements should be recorded for the integration with the module and maintain a continuous
operation for serving the users. The integration of the modules helps in identification of the
errors at the early stage of the development and helps thee development team to deliver a quality
software product by reducing the errors in the system. The implementation phase takes longer
time than the development phase because different modules are required to be integrated with
each other for interoperability and eliminating the risk associated with the development of the
project.
The maintenance phase consists of the different types of services such as database
maintenance, updating the operating system and application of patches for removing the flaws in

the current system. The permission for accessing the resources are also managed in this phase
according to the changes in the needs of the car parking system.
