ADI Assignment Spring Winter 2023 FINAL.pdf

  1. 1. Unit: Analysis, Design and Implementation Assignment title: Expense Tracker Spring – Winter 2023 Important notes ● Please refer to the Assignment Presentation Requirements for advice on how to set out your assignment. These can be found on the NCC Education website. Hover over ‘About Us’ on the main menu and then navigate to ‘Policies and Procedures’ then scroll to the ‘Student Support’ area. ● You must read the NCC Education document Academic Misconduct Policy and ensure that you acknowledge all the sources that you use in your work. These documents are available on the NCC Education website. Hover over ‘About Us’ on the main menu and then navigate to ‘Policies and Procedures’ then scroll to the ‘Student Support’ area. ● You must complete the Statement and Confirmation of Own Work. The form is available on the NCC Education website. Hover over ‘About Us’ on the main menu and then navigate to ‘Policies and Procedures’ then scroll to the ‘Student Support’ area. ● Please make a note of the recommended word count. You could lose marks if you write 10% more or less than this. ● You must submit a paper copy and digital copy (on disk or similarly acceptable medium). Media containing viruses, or media that cannot be run directly, will result in a fail grade being awarded for this assessment. ● All electronic media will be checked for plagiarism.
  2. 2. Page 2 of 5 Analysis, Design and Implementation © NCC Education Limited 2023 Scenario A local bank has asked the software development company you work for to develop an expense tracking system for their customers. Tracking expenses is often the first step in getting people’s finances in order. If you do not know how much you have spent each month, you cannot tell when you have overspent. By understanding what you spend money on and how much you spend, you can see exactly where your cash is going. The company has handed the responsibility for its development on to you. You should write a program that implements an expense tracking system. Your program should allow the bank customers to create an account with a username and password. The usernames can only contain letters and numbers. The password must be at least EIGHT (8) characters long, and contain at least ONE (1) lowercase and ONE (1) uppercase letter. Once they have logged in, your program should present them with a welcome page with FOUR (4) different expense categories. Examples of expense categories can be found in the table below. Note you need to reflect on your own life experiences and learn about your own spending habits to be able to decide FOUR (4) expense categories of your own for the system. Examples of Expense Categories Home Insurance Transport Saving Family Health Clothes Education Food Customers should be able to record expenses into their respective categories. Under each category, customers can add a new expense item, edit and delete an existing expense item. For example, add a new grocery expense to the food category, or delete a recorded gift purchase for a family member from the Family category. A summary of details of all recorded expenses of the customer’s choice should be displayed to customers. Details of each expense should include ● month - day or year is NOT required. ● cost - the amount of money ● payment type - credit card, debit card, or cash ● description - a short note The system should be able to create a bar chart showing the customer’s monthly breakdown expenses by category. The bar chart is to present the monthly expenses (the sum of costs) of each category with rectangular bars. The bars can be plotted vertically or horizontally. The bars’ heights or lengths are proportional to the monthly expenses of each category that they represent. For example, if you create a vertical bar chart, the bar height should be proportional to the total expenses and the bar width should be fixed. The bar chart should be properly labelled with title, x - and y - axis. See an example below.
  3. 3. Page 3 of 5 Analysis, Design and Implementation © NCC Education Limited 2023 Your program will need to perform the following operations: ● Set up the GUI ● Allow customers to create a new account ● Allow existing customers to log in their account to: o record expense details o add a new expense - record date (month only), cost, description, payment type. The item details should be displayed to customers after it’s been added o amend an existing expense – date (month only)/cost/description/payment type. An update with details should then be displayed to the customer; o and delete an existing expense ● Create a bar chart for monthly breakdown by category ● Provide appropriate errors and help messages, and guidance for customers. Task 1 – 20 Marks Class Diagram Draw a Class Diagram to represent the system structure. The Class Diagram should be drawn with a suitable CASE tool and show attributes, operations, scope and relationship of classes to each other with multiplicity. The use of abstract classes and sub-classes (where appropriate) will attract additional marks. Provide a justification why each class was selected for inclusion, and how its relationship to other classes was derived.
  4. 4. Page 4 of 5 Analysis, Design and Implementation © NCC Education Limited 2023 Task 2 – 20 Marks Activity diagram Draw an activity diagram to show the classes involved when a user wants to create a new account. Show which function each class is associated with. Task 3 – 10 Marks Use case diagrams Draw a Use-Case Diagram to capture the requirements listed in the scenario. Task 4 – 40 Marks System implementation Write and deploy code to implement your system design for the requirements listed in the scenario. The code should appropriately handle input and output. Your software should implement GUI that allows users to perform all the operations required above. Consider an appropriate level of coupling and cohesion between the classes and any inheritances and encapsulations that represent the system. All code should be written in C# for this assignment. Task 5 – 10 Marks Software Quality Write a short report of 500 words answering the following two questions concerning the coupling and cohesion principles. a) Discuss different types of coupling and cohesion. b) Describe how the coupling and cohesion principles have affected your program design.
  5. 5. Page 5 of 5 Analysis, Design and Implementation © NCC Education Limited 2023 Submission requirements ● Your program must be submitted as a zip file of the full project. o No marks will be awarded for code written in a language other than C#. o Whatever IDE you use, it should be possible to open and run the project directly from the extracted archive. ● Diagrams and materials associated with the tasks above should be presented in a word-processed document. ● All references and citations must use the Harvard Style. Candidate checklist Please use the following checklist to ensure that your work is ready for submission. Have you read the NCC Education document Academic Misconduct Policy and ensured that you have acknowledged all the sources that you have used in your work? ❑ Have you completed the Statement and Confirmation of Own Work form and attached it to your assignment? You must do this. ❑ Have you ensured that your work has not gone over or under the recommended word count by more than 10%? ❑ Have you ensured that your work does not contain viruses and can be run directly? ❑
