and functions:

1. Create three identities in Google datastore (Namespace: user, Kind: user), which contain the following properties and
values. 1 mark

id (Type: Key) name (Type: String) password (Type: Integer)
s3######
i.e. your RMIT student id
Firstname Lastname
i.e. your name
123456
i.e. your RMIT student id
s3######1
i.e. your RMIT student id+’1’
Firstname Lastname A
i.e. your name+’A’
234567
s3######2
i.e. your RMIT student id+’2’
Firstname B Lastname B
i.e. your name+’B’
345678

2. login.php 2 marks
A login page that contains a user id field, a password field, a “Log In” button. When user clicks the “Log in” button, it will
validate if the user entered credentials match with the information stored in the datastore.
• If the user credential is invalid, the login page will display “User id or password is invalid”. 1 mark
• If the user credential is valid, it will be redirected to main.php. 1 mark

3. main.php 2 marks
The main page contains two buttons “Change Name” and “Change Password”.
• The main page shows the user name 1 mark
• If user clicks the “Change Name” button, it will be redirected to the name.php; if user clicks the “Change
Password” button, it will be redirected to the password.php. 1 mark

4. name.php 2 marks
The name page contains a username field and a “Change” button, where user needs to enter a new user name
• Once user clicks the “Change” button, it will validate whether the entered user name is empty. If the user name is
empty, it will display “User name cannot be empty ”. 1 mark
• If the user name is not empty, it will update the corresponding entity in Datastore and be redirected to main.php,
where the user name on main.php will also be updated. 1 mark

5. password.php 2 marks
The password page contains an old password field, a new password field and a “Change” button, where user needs to
enter both the old password and a new password.
• If user clicks the “Change” button, it will validate whether the entered old password matches with the

This task is based on Google Big Query that we covered in Lab 3.

Using the baby_names dataset you created in Lab 3 write some queries (using BigQuery browser tool) to identify the
following information (Each correct query 1 mark)

1. Find a list of all male babies born before 2010 with frequency count ends with ‘00’ (i.e. 100, 200, …). 1 mark

2. Find top 10 years after 1999 with the highest number of female baby names containing ‘ie’ (case-insensitive). 1 mark

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
3. Code of task-2
4. Queries of task-3

Make a .zip of your text file and submit it into Canvas→Assignments→Assignment 1 before the deadline. You will be marked
during your demo time. This submission is only for keeping the records. However, you will not able to view your mark in
Canvas until you submit your file.
7. 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:
• 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:
