Question

In this assignment, you are required to complete the followings to validate your system designs.
You have the following two choices to develop detailed object-oriented design models. You also need to submit a proper documentation describing the different aspect of developed component, within 2000 words.

Task 1: The students who have expertise in object-oriented programming are required to validate their system design through developing a prototype for at least one subsystem of chosen case study. You have an option to use any object-oriented programming language such as C++, Java, C#, etc. to develop this subsystem.

OR

Task 2: The students who have no expertise in object-oriented programming are required to validate their system design using interaction diagrams (i.e., communication diagrams or sequence diagrams) for at least one subsystem of chosen case study. To do this, identify3 (three) most importantuse cases for the subsystem and develop communication diagrams or sequence diagrams for these use cases.

Rationale

The purpose of this assessment task is to develop student's skills and knowledge in:

•Validating an OO design through the construction of a prototype (Learning outcome 1)
•Converting design diagrams into program code (Learning outcome 8)
•Preparing project documentation (Learning outcome 4 - 6)
•Developing presentations, and through peer review to reflect on their own practice and improve their design (Learning outcome 8)

OR

The students who have no expertise in object-oriented programming are required to validate their system design using interaction diagrams (i.e., communication diagrams or sequence diagrams) for at least one subsystem of chosen case study. To do this, identify all possible use cases for the subsystem and develop communication diagrams or sequence diagrams for these use cases.

Task 1:
Fully functional prototype using major principles of object-oriented programming such as encapsulation, data abstraction, polymorphism and inheritance. Each variable, function/method, loops, if/else statements, etc are well commented.

OR

Task 2:
All possible use cases of the subsystem are identified; developed communication or sequence diagrams are correctly showing logical flow of the system activities, input/output messages, and accurate symbols/notations.

Task 1:
Mostly fully functional prototype using major principles of object-oriented programming such as encapsulation, data abstraction, polymorphism and inheritance. Each variable, function/method, loops, if/else statements, etc are well commented.

OR

Task 1:
Prototype not always functional using major principles of object-oriented programming such as encapsulation, data abstraction, polymorphism and inheritance. Each variable, function/method, loops, if/else statements, etc are not well commented.

OR

Task 2:
Some use cases of the subsystem are identified; developed communication or sequence diagrams are mostly correct showing logical flow of the system activities, input/output messages, and accurate symbols/notations.

Task 1:
Prototype has major errors and not working.

OR

Task 2:
Few use cases of the subsystem are identified; developed communication or sequence diagrams are wrong.

Submit a proper documentation describing the different aspect of developed component, within 2000 words.

Introduction
Collin’s car parking system has many car parks around the city. The parking systems of all car parks are manually operated by the staff members. There is requirement to model a system by applying the objected oriented system development methodology to automate the car parking system of Collin’s car parks. The object oriented methodology for the system development starts with the analysis of requirements and then specification. There are various approaches applied to analyze the system requirements of car park. 
A use case diagram is developed to identify the requirements of the system by inclusion of the users of the system. Use case diagram is a model that defines the various system processes that are performed by the users. There are use cases and that use cases are used by the actors of the system. After modeling the use case diagram a static model such as class diagram is develop to represent the objects and classes of the system and their relationship between each other. This static model includes classes and their attributes and operations. 
When the static model such as class diagrams are developed for the car parking system then behavioral model is required to be developed under the object oriented system development methodology. A behavioral model is a indicates the states of the objects and events. Once the event occurred with an object then object goes into the transition phase and states of the object changes with respect to the events.
There are so many methods to model the behavioral model such as activity diagram, communication diagram, sequence diagram etc (Coplien & Bjørnvig, 2010). These all models state the behavior of the object with respect to events and transitions.
Sequence diagram is an interaction diagram that models the interactions between the objects of the system like objects of the Collin’s car parking system. There are so many object identified from the problem domain of the Collin’s car parking system. These objects are detailed as follows.
Customer – This object represents the car parking customers. There are two categories of customers like ordinary customers and fixed ticket holder customers.
Ticket – The ticket is an object that represents the identity for entry into the car park. This is just like a token that contains the car details and time and date. Ticket is also of two types, one is for fixed ticket holder customer and another is for the ordinary customer.
Parking Fee – An object that represents the fee details of the car parking having the time, date, day and charges of parking fee with respect to day and shift on hour basis for ordinary customer and on weekly, monthly and yearly basis for fixed ticket holder customer.
Payment – An object that holds the details of payment mode and payment amount for the car parking of Collin’s car park.
Control Pillar – An object that holds the information for button activity, light signal, sensor activity etc. 
Barrier – An object that holds the information like open and close state. 
Ticket Printer – An object that prints the tickets for the ordinary customer and fixed ticket holder customer.
Database – An object that holds all the information related with Car Staying in the car park, ticket information, customer details etc.
Subsystem selected from the problem domain is Access to Car Park
The sub system access to car park is one of the main sub system of the Collin car parking system. The whole system is a automated car parking system where no manual processes are deployed so that system provides the ease to the customer to do parking related activities self with automated system activities.
The system objects involved with the development of Interaction such as Sequence diagrams are Ordinary customer, fixed ticket holder customer, control pillar, ticket printer, barrier and database. Some of these objects are actors of the system under the sequence diagram.
Use Cases of the selected sub system
There are three main use cases are selected to develop the interaction diagram. The sequence diagram is developed for the behavioral model such as Interaction diagram. These use case are as follows.
