This is an individual assessment. You must not collaborate or confer with others. You 
may help others by verbally explaining concepts and making suggestions in general 
terms, but without directly showing or sharing your own code. You must develop the 
logical structure, the detail of your code and the database on your own, even if you are 
working alongside others. Code that is copied or shares a similar logic to others will 
receive zero marks for both parties. 
 
The use of Artificial Intelligence (AI) tools, such as ChatGPT, to complete this assessment 
is prohibited. Assessment answers will be analysed for evidence of the use of AI and 
penalties may be administered.

Introduction 
Your task is to create a Python application which uses the model classes that you have 
designed in the first part of this project. Please refer to the feedback provided for the first 
part to improve your design. Alternatively, you may you use the class diagram shown in 
Appendix A. Note that this is a simplified class diagram and shows the attributes only (and 
not the methods). You may also add additional attributes to each class as you see fit. 
You are required to code your design (possibly amended after feedback) and create a GUI 
(using tkinter or Flask and Python) that works with your design. You will also write test cases 
to verify the functionalities of your software application. 
Customers should be able to place orders, view their current orders and past orders, cancel 
current order (if the order is not processed yet), make payments, and view their information. 
Staff should be able to view current orders, fulfil the orders, and update the status of the 
orders. Staff can also use the application to generate several reports for the company. COMP642 | OO programming Software Design | Page 2 
Requirements 
1. Adapt your design from Project Part 1 as necessary, so that the following 
functionalities can be implemented for customers and staff. You will need to use 
SQLAlchemy to store the objects to a MySQL database. 
Customers can: 
1. Log in and Log out. 
2. View available vegetables and premade boxes. 
3. Place order for vegetables and premade boxes. Premade boxes need to be 
assembled based on the size. At checkout, pay for the item using credit card or 
debit card or charge the amount to their account. 
4. View current order details. 
5. Cancel current order if the order has not been fulfilled. 
6. View previous orders details. 
7. View their own details. 
Staff can: 
1. Log in and Log out. 
2. View all vegetables and premade boxes. 
3. View all current orders and their details. 
4. View all previous orders and their details. 
5. Update an order status. 
6. View all customers and their details. 
7. Generate a list of all the customers. 
8. Generate the total sales for the week, month, and year. 
9. View the most popular items. 
 
2. Implement an appropriately designed view. Your view should be an interface with 
appropriate controls, useful feedback, and exception handling. You may use tkinter 
or web application to implement the view. 
3. Perform error handling and prevention mechanisms to ensure that the application is 
robust, reliable, and resilient. 
4. Write and test your code for all the model classes and other components in your 
design using pytest. 
5. Your code must be clear and easy to maintain, and appropriately commented. 
6. Your application does not have to provide facilities for staff to add new 
customers/vegetables, delete existing customers/vegetables, or amend 
customer/vegetable details. It also does not have to provide facilities for a customer 
to amend their details.

Marking Criteria 
Criteria Marks 
(out of 140) 
Mark Range 
Application functionalities: 
Customer (20) 
Staff (20) 
40 Marks will be assigned using the following criteria: 
All requirements met (81% - 100%) 
Some requirements met (51% - 80%) 
Minimum requirements met (1% - 50%) 
Application Interface 
 
 
10 Excellent user interface, intuitive, and user friendly. 
Widgets are well-chosen, effectively implemented, 
and enhance the user experience (9 – 10). 
The user interface is intuitive and user-friendly. 
Widgets are mostly appropriate and functional but 
may have minor usability issues (7 – 8). 
The user interface provides basic functionality but 
lacks in intuitiveness and user-friendliness. Widgets 
may be poorly chosen or implemented, leading to 
confusion or difficulty in their use (5 – 6). 
The user interface is not intuitive or user-friendly. 
Widgets are poorly chosen or implemented (1 – 4). 
Error Handling and Preventions 10 All relevant errors are detected and handled 
appropriately (9 – 10). 
Some errors are detected and handled 
appropriately but may miss some less common 
issues (5 – 8). 
Minimal or ineffective error detection; many errors 
are not identified (0 – 4). 
Testing 10 Comprehensive test coverage with all relevant 
areas of the application thoroughly tested, 
including edge cases (9 – 10). 
Most key areas are tested, though some gaps may 
exist. The test suite covers essential functionality 
and interactions but might miss a few edge cases 
or less common scenarios (5 – 8). 
Significant gaps in test coverage, with critical areas 
or edge cases often untested. The test suite lacks 
depth and fails to cover many aspects of the 
application (1 – 4). 
Code 70 See Code Evaluation Rubric.

Attribute High (8 -10) Moderate (4 – 7) Low (0 – 3) 
Code Quality 
Correctness (10) 
The code is free of bugs 
and meets all 
requirements. 
The code mostly 
functions correctly with 
some minor bugs or 
edge cases not fully 
addressed. 
The code contains 
significant bugs or errors 
affecting functionality. 
Code Quality 
Standards (10) 
The code strictly follows 
best practices ensuring 
robust, secure, and 
reliable code. 
The code generally 
follows standards but 
has minor deviations or 
inconsistencies. 
The code does not 
adhere well to standards 
is inconsistent and 
prone to issues. 
Readability and 
Maintainability 
Readability (10) 
 
The code is highly 
readable with clear 
variable names, 
consistent formatting, 
and well-organised 
structure. Complex logic 
is well-documented. 
 The code is generally 
readable with mostly 
clear names and 
comments. There may 
be minor issues with 
formatting or 
organisation. 
The code is difficult to 
read, with unclear 
names, inconsistent 
formatting, and 
insufficient comments. 
Understanding and 
maintaining the code is 
challenging. 
Readability and 
Maintainability 
Maintainability (10) 
 
The code is modular and 
easy to maintain, with 
clear separation of 
concerns and minimal 
risk of introducing new 
issues when updating. 
 The code is somewhat 
maintainable but may 
require effort to update 
or extend. Some areas 
could be improved for 
better modularity. 
The code is hard to 
maintain or update due 
to poor structure and 
lack of modularity. 
Changes are likely to 
introduce new issues or 
require significant effort. 
Comments 
Clarity (10) 
Comments are clear, 
concise, and provide 
meaningful explanations 
of complex logic. They 
enhance understanding 
without stating the 
obvious. 
Comments are mostly 
clear but may be slightly 
redundant or lack detail 
in some areas. 
Comments are unclear, 
inconsistent, or 
insufficient, making it 
difficult to understand 
the code. 
Comments 
Coverage (10) 
Comments 
comprehensively cover 
key sections of the code, 
including purpose, 
functionality, and nontrivial
implementations. 
Comments cover most 
key sections but may 
have minor gaps or areas 
where additional detail 
would be useful. 
Comments are sparse or 
missing, leaving key 
sections of the code 
poorly explained or 
undocumented. 
Efficiency (10) The code is highly 
efficient and welloptimised,
 balancing 
performance with 
readability and 
maintainability. 
The code is reasonably 
efficient but may have 
some areas for 
improvement. It is 
somewhat optimised but 
could benefit from 
refinements. 
The code is inefficient, 
either due to a bruteforce
approach or being 
overly complex and 
patched together. It 
lacks effective 
optimisation and 
resource management.
