matches with the information stored datastore. If the old password is incorrect, it will
display “The old password is incorrect”. 1 mark
6.1.2. If the old password is correct, it will update the user password stored in the Google
Datastore/Firebase and be redirected to the login page, where user can login with the
new password. 1 mark
6.2. The user post edit area
6.2.1. displays all the message information (message subject and posting date and time)
posted by the login user. Each message is followed by an “Edit” button. 1 mark

Important Notes:
1. The whole application must be COMPLETELY programmed by yourself. You CANNOT use any
external source code.
2. The whole application must be FULLY deployed in Google App Engine, otherwise NO MARK
will be given for Task 1-3 to Task 1-6.

Task-2 [6 marks]
This task is based on Google BigQuery that we covered in Tute 3.

1) Use the a1_2 dataset (three csv files: gsquarterlySeptember20, services_classification,
country_classification) to write some queries to retrieve the following information.
2) Use BigQuery API Client Libraries to create an application based on your queries. (Note: This is
a compulsory requirement otherwise Task-2 WON’T be marked).
3) Deploy your application in your Google App Engine so that the query results can be displayed
on the webpage once you type in your Google App Engine URL (Note: This is a compulsory
requirement otherwise Task-2 WON’T be marked).
(Each correctly displayed query result is worth 2 marks)
1. Show top 10 time slots (year and month) with the highest trade value (i.e. import value + export
value). 2 marks
Note: Show “time_ref” and “trade value” in your results.

2. Show top 50 countries with the highest total trade deficit value (i.e. import value - export value) of
goods from 2014 to 2016 where status is “F”. 2 marks
Note: Show “country_label” (full country name), “product_type”, “trade deficit value” (in a
descending order), and “status” in your result.

3. Show top 30 services with the highest total trade surplus value (i.e. export value - import value) in the
top 10 time slots of Query Result 1 and the top 50 countries of Query Result 2. 2 marks
Note: Show “service_label” (full service name) and “trade surplus value” (in a descending order) in your
result.

Task-3 [1 mark]
Write at least 100 words to describe the preliminary plan of your Assessment 3 (to be released in early Week
5), including the motivation, the objective, the possible system components, the proposed functions and the
possibly adopted AWS services and/or external APIs for each component.

Note:
1) References should be included when needed (excluded in the word count);
2) This task is only designed to encourage you to start preparing your Assessment 3 early. We won’t assess
the quality of Task-3 content. You may discuss the details of your preliminary plan with your tutor in weekly
workshops.

5. Referencing guidelines
What: This is an individual assignment, and all submitted contents must be your OWN. If you have used
sources of information other than the contents directly under Canvas→Modules, you must give acknowledge
the sources and give references using IEEE referencing style.
Where: Add a code comment near the work to be referenced and include the reference in the IEEE style.
How: To generate a valid IEEE style reference, please use the citethisforme tool if unfamiliar with this style.
Add the detailed reference before any relevant code (within code comments).
6. Submission format
Create a .txt file and name it [your_student_number].txt (e.g. s3369312.txt). This .txt file will contain items
in following order

1. Your Name and student number
2. Code of Task 1 (app.yaml, py/html/php files)
3. Code of Task 2 (app.yaml, py/html/php files)
4. Texts of Task 3

Submit it into Canvas→Assignments→Assessment 1 before the deadline. You will be marked during
your demo time. This submission is only for keeping the records. However, your assessment will NOT
be allowed to be demonstrated in Canvas until you submit your file.
7. Demonstration
You must demonstrate your project online to an available tutor (unnecessarily your tutor) by making an
appointment with the tutor in Week 6. The demo booking will be made available to students in Week 5. All
demonstrations must be completed by Week 6. There will be penalty if you fail to complete and
demonstrate your work by Week 6. The demo is around 15 minutes for each student. Keep everything
ready and make your application live (on 2 Google Cloud projects) during your demo.
Note: Each student can only attend one demonstration for Assessment 1. DON’T overbook otherwise you
will receive penalty. If you are not satisfied with your mark, you may attend the online remarking session
organized by the course coordinator after Week 6 (remarking time and booking will be made available to
students through announcements).
8. Academic integrity and plagiarism (standard warning)
Academic integrity is about honest presentation of your academic work. It means acknowledging the work
of others while developing your own insights, knowledge and ideas. You should take extreme care that you
have:
,

RMIT Classification: Trusted
• Acknowledged words, data, diagrams, models, frameworks and/or ideas of others you have quoted
(i.e. directly copied), summarised, paraphrased, discussed or mentioned in your assessment
through the appropriate referencing methods,
• Provided a reference list of the publication details so your reader can locate the source if necessary.
This includes material taken from Internet sites.
If you do not acknowledge the sources of your material, you may be accused of plagiarism because you have
passed off the work and ideas of another person without appropriate referencing, as if they were your own.
RMIT University treats plagiarism as a very serious offence constituting misconduct. Plagiarism covers a
variety of inappropriate behaviours, including:
• Failure to properly document a source
• Copyright material from the internet or databases
• Collusion between students
For further information on our policies and procedures, please refer to the University website.
9. Assessment declaration
When you submit work electronically, you agree to the assessment declaration.
