ISCG7420 Assignment 1 Solved

Total Marks: 100 Course Weighting:

2. Discuss the tools used in providing web-based applications.
3. Design and implement a dynamic web application using a range of

   languages/technologies/tools.

4. Discuss and evaluate the available data access technologies.

Assignment information:

•   This is an individual assignment.
•   Read the given scenario and complete the two tasks.
•   For Task 1 you will evaluate two programming languages and two data access

  technologies and present your findings within a count of 1000 words [+/- 10%],

  excluding reference list.

•   For task 2 you will design and implement a Django web application. Firstly, you will identify the Django models, then create views and templates.

  Assignment Submission:

•   Upload your response for task 1 in word format to Moodle “assignment 1-task 1 submission link”.
•   For task 2 use the Assignment 1 directory of your class GitHub repository to store your task and add your lecturer as a collaborator. Periodically throughout the course your lecturer will clone your repository to check your progress. On the assignment due date (and for up to 72 hours afterwards) your lecturer will download the most recent version of your task 2. You are required to ensure that GitHub always has the latest version of your code.
•   For task 2 if you forget to push your most recent changes by the due date, then your lecturer will use the latest version available on GitHub when the deadline is reached for marking. Make sure you regularly update files. If you use and submit code that you didn’t write, you will fail this assignment, and fail the course. Ask your lecturer for help long before the due date instead of plagiarising.

Task 1: Technology Evaluation [16 Marks]

Before you start web development (i.e., in this case gradebook system) you will do research and evaluate programming languages and data access technologies that can used for the development. Answer the following questions.

Questions

1. Evaluate two web programming languages that can be used for this development.
2. Evaluate two data access technologies can be used for this development.
3. Based on your evaluation of questions 1 and 2 recommend a web programme

   language and data access technology that can be used for development.

Task 2: Web Development [85 Marks]

To develop the gradebook system, you need to design and implement a dynamic web application using Django, PostgreSQL and/or other available web development tools. You will also host your web application on Heroku with available add-ons. You will upload your code to GitHub. The requirements for the application are given below:

Part A – Models [36 marks] Follow the given class diagram to create models

Late Submission of Assignments:

Assignments submitted after the due date and time without having received an extension through Affected Performance Consideration (APC) will be penalised according to the following:

•   10% of marks deducted if submitted within 24hrs of the deadline,
•   20% of marks deducted if submitted after 24hrs and up to 48hrs of the deadline,
•   30% of marks deducted if submitted after 48hrs and up to 72hrs of the deadline,
•   No grade will be given for an assignment that is submitted more than 72hrs after the deadline.

  Assistance to other Students:

  Students themselves can be an excellent resource to assist the learning of fellow students, but there are issues that arise in assessments that relate to the type and amount of assistance given by students to other students. It is important to recognise what types of assistance are beneficial to another’s learning and also what types of assistance are unacceptable in an assessment.

  Beneficial Assistance:

•   Study Groups
•   Discussion
•   Sharing Reading Material
•   Reading the available online and library resources

  Unacceptable Assistance:

•   Working together on one copy of the assessment and submitting it as own work
•   Giving another student your work
•   Copying someone else’s work, this includes work done by someone not on the course
•   Changing or correcting another student’s work
•   Copying from books, the Internet etc. and submitting it as own work; anything taken directly from another source must be acknowledged

  correctly; show the source alongside the quotation

•   Don’t copy code from a website or video tutorial and pretend you made it or slightly change it. This will be an instant fail (0%).

Appendix 1
Sample Project Ideas (Simple versions):

1. Instagram clone
2. Facebook clone
3. Twitter clone
4. YouTube clone
5. Pinterest clone
6. Reddit clone

You must identify and construct the models required by most modern web applications. Example functionality is for example: making posts, uploading images, liking posts, comments, sending messages, adding a tag to a post, notifications, login/logout, etc.

If you choose to do something different you need to get approval from your lecturer.
Communicate with your lecturer during the course to ensure your application meets the required guidelines and marking schedule.

Appendix 2
Developer Journal Example:

===
March 23rd 2020 – Started @ 2:30PM
Going to work on Task #5, to try and implement saving user data to text files. Estimate: 30 minutes

Got a bug, file isn’t being created correctly.
5:15PM Still stuck on bug. Switching to Task #7 to add a button. 5:45PM Added a button, closed Task #7.

7PM: Fixed bug with file not being created. I was accidentally saving it to the wrong directory. Future Suggestion: Make sure to always check which directory I save files to.
Actual time taken: ~4 hours.

7:30PM: Need to create an Invoice class which has save() method. Estimate: 1hr

Stopped @ 9pm.
===
March 24th 2020 – 10AM
Continuing on Task #6 from yesterday – Creating class for Invoice

10:30AM: Finished class for Invoice (Task #6). Actual time taken: ~2 hours.

10:45AM: Debug Issue #12 – Game collisions aren’t working and object disappears off screen. Estimate: 4 hours

1PM: While debugging game collisions I realized that I forgot to enable logging. I enabled logging and instantly saw why collisions weren’t working. I wasn’t checking if a collision occurred before moving the object.
Future Suggestion: When creating classes, start with a list of pseudo-code comments of things I need to remember to check. Also don’t forget to enable logging when debugging.

Actual time taken: ~2 hours
2PM: Refactored / rewrote the do_stuff() function to be smaller and more clear.

4PM: Found a StackOverflow post for a possible solution to Task #9: https://stackoverflow.com/questions/1077347/hello-world-in- python

5PM: Solution didn’t work. Out of time for this feature so will cut it and work on a different task. Etc.. Write in your journal and work on your code daily.
