Introduction
The case study is about the analysisof the students’ understanding in analyzing a given scenario and practical skills to apply concepts and build diagrams studied in IT242 (Software Engineering). The case studyconsists of five parts. Studentsarerequired to answer all of these parts based on the below scenario.
The transformation from traditional commerce to E-commerce has several advantages such as less cost, process time and mistakes.“ MyBook ”, a bookstore that sells used books, is in the process of expanding its business. In order to achieve this plan, the “MyBook” administration would like to start developing a Website(as a virtual bookstore)with the following scenario:
The “MyBook” administration wishes to have a responsive website that renders well on desktop and mobile devices. The Website visitors would be able to view the available used books and if they would like to buy books, they have to register in the system and become customers for this bookstore. When a customer creates his/her account, the customer’susername and passwordmust be selected. After logging to the system, customers can search for available used books, view the table of contents, order books and pay online after providing the credit card details. Additionally, customerscan submit complaints. The system should verify the customer’s user name and password. The system also verifies the credit card details, if approved, the customer’s order is finalized, and the system sends aconfirmation email to the customer.
The “MyBook” employee is responsible for handling the customer orders, addingused books, and updating the customer details. The employee will be able to do suchtasks only after logged into the system. The “MyBook” manager can check the status of the online customers’ orders, check the list of available used books, withdraw old or damaged books, and update employees’ details. In addition, the manager can announce special or seasonal discount offers, for example, discount offers on purchases on the Saudi National Day. The manager will be able to do all such tasks only after logged into the system. Adelivery employee can login to the system and view and deliver the book orders that are ready for delivery. The “MyBook” administration would like to have a system that allows the customers to pay by credit card or upon delivery (Cash on delivery – COD).The system should be available for use 24 hours per day, 365 days per year.
Deliverables
The parts of thiscase studyyields many outputs. These outputs will be the means of evaluation of each part of the case study. On or before the due date, the group leader (selected by the students’ group) must upload only one Word-format document to the Blackboard.
Based on the given scenario, answer the following parts.
( 12 Marks ) ( Learning Outcome(s): LO4 )Part One
Questions of this part analyze the students’ understanding in analyzing the given scenario to identify functional requirements (FRs), non-functional requirements (NFRs), and practical skills to build use case diagrams studied in chapters 8, and 9 of IT242.
1.1 List two functional requirements (FRs).(2 Marks)
1.2 List two non-functional requirements (NFRs). (2 Marks)
1.3 List the actors of the proposed Website. (2 Marks)
1.4 Draw a use case diagram for the given scenario.(6 Marks)
Answer:
( 8 Mark s ) ( Learning Outcome(s): LO2 )Part Two
Questions of this part analyze the students’ understanding in analyzing the given scenario and practical skills to build Swimlane diagrams studied in Chapter 9 of IT242.
The following paragraph depicts the activity of handling the delivery of books initiated by the delivery employeeand mentioned in the “ MyBook ” scenario. Draw a Swimlane Diagram for the given activity.(8 Marks)
The process starts when the delivery employee logins to the system. The system verifies his/her credentials. If correct, he/she can proceed otherwise he/she gets two other chances and after that the process ends. The delivery employeeviews all the books that he/she is supposed to deliver then enters what time he/she will come to pick them up. The delivery employeecan also reject the delivery job. If he/she accepts the job, the system sends a message to the “MyBook” delivery handling employee about the time in which the delivery employeewill come to pick up the books, thenthe process ends. If the delivery employeerejects the job, the system sends an alert to the “MyBook” Manger. The Manager assigns the job to another delivery employeeand the process ends.
Answer:
( 1 4 Marks ) ( Learning Outcome(s): LO 2 and LO 3 )Part Three
Questions of this part analyze the students’ understanding in analyzing the given scenario and practical skills to build Class diagrams studied in chapters 8, 10 and 12of IT242.
The “ MyBook ” administration would desire to have a database system to keep track of itsemployees, books, customers and online orders. Read the following paragraph to answer the given questions.
The system maintains employees’ information. For each employee, the system keeps a unique employee ID, name, address, contact number and salary.Thesystem also stores customers’ information. Each customer has a customer ID, name, title, contact number, and address.Each customer can makezero or more orders. Each order has an order ID, date and method of payment. A single order is associated with one or more used books. The used books are stored in the bookstore inventory. The bookdetails to be stored are ISBN, title, author, publisher, publication year,quantity and unit price.An order is processed by one or two employees.A single order is also associated with zero or one discount. A discount has a discount ID, discount percent, discount code, start date and end date.A discount is managed by one employee only.A customer can file zero or more complaints. Each complaint has a complaint ID, title, body and date. A complaint is handled by one or more employees.
3.1 Identify the classes and their attributes from the given paragraph. (6 Marks)
3.2 Draw a Class diagram for the given database. The diagram must show all classes, relationships between classes, and multiplicities.(8 Marks)
Answer:
( 7 Marks ) ( Learning Outcome(s): LO3 )Part Four
Questions of this part analyze the students’ understanding in analyzing the given scenario and practical skills to build State diagrams studied in Chapter 12 under the Design Model.
4.1 The used book has different price statuses. During the national celebration days, the price of any book is 40% off, while on the day of returning to the university it is 30% off. For other normal days, the book has a normal price. Draw a UML state diagram for the used book. The diagram must show the guards.(7 Marks)
Answer:
( 9 Mark s ) ( Learning Outcome(s): LO1, LO4, and LO5 )Part Five
The question of this part analyzes the students’ understanding in analyzing the given scenario and use brainstorming to apply and reflect concepts studied in chapters 4, 5, 6, 7, 19 and 22 of IT242.
All software process models can accommodate the generic framework activities (communication, planning, modeling, construction, and deployment), but each applies a different emphasis to these activities and defines a process flow that invokes each framework activity in a different manner.
5.1 Suppose you have been assigned, as a group, the tasks of project manager and software engineers to adopt a process model to develop the scenario given in the case study, which process model do you choose? Explain your answer. (5 Marks)
5.2 If the customer needs to be fully satisfied with the website interface, what is the process model do you recommend for developing the scenario? Explain your answer. (4 Marks)
