Task 2 [11 marks] using the Pulse Learning database

For task 2, we have provided you with the creation script for the Pulse Learning database. You must run this script in MySQL Workbench and use this database to extract the necessary information.

The script is based on the following schematic:

PULSE LEARNING relational model

Student (studentID, firstName, surname, email, streetNo, streetName, suburb, city, postcode, state, watchType, watchSerial#, buddyID)

PhoneNumber (phoneNumber, studentID)

Unit (unitID, unitName, unitCode, semester, year)

Enrolments (unitID, studentID)

UnitTutor (staffID, unitID)

Assignment (assignmentID, assignmentName, dueDate)

Grade (studentID, assignmentID, grade)

Lecture (staffID, firstName, surname, email)

SleepPatterns (sleepID, studentID, date, timeAsleep, timeAwake)

FOREIGN KEYS

? Enrolment (studentID) is dependent on Student (studentID)

? Enrolment (unitID) is dependent on Unit (unitID)

? Enrolment (staffID) is dependent on Lecture (staffID)

? StudentSleepPatterns (studentID) is dependent on Student (studentID).

? StudentSleepPatterns (sleepPatternID) is dependent on SleepPatterns (sleepPatternID)

? StudentAssignment (student ID) is dependent on Student (studentID)

? StudentAssignment (assignmentID) is dependent on Assignment (assignmentID)

? PhoneNumber (studentID) is dependent on Student (studentID)

OTHER CONSTRAINTS

? Student (state) domain is [QLD, SA, TAS, NSW, WA, NT or ACT]

? SmartWatch (type) domain is [FitBit, Suunto, Apple Watch or Samsung Gear]

? Students may have up to three phone numbers

Query 1 (1 mark) Write a query to list the name (first and last), studentID and email of students who live in Everton Park or Everton Hills. Note: you can assume these are the only suburbs starting with Everton.

Query 2 (1 mark) Write a query to list students with buddies, in alphabetical order by surname.

Query 3 (2 mark) Write a query to count how many units each lecture teaches. In your result-set, include the lectures staffID, firstname, surname and the number of units they teach.

Query 4 (2 marks) Write a query that will produce some statistics about assignment results. Your result-set should include the following:

? the assignment ID

? the assignment name

? the minimum grade achieved by the class for an assignment

? the average grade achieved by the class for an assignment

? the maximum grade achieved by the class for an assignment

? the number of submissions received.

Query 5 (2 marks) Write a query that lists the full name and email address of all lectures that arent teaching any classes next semester (Semester 2, 2018).

Query 6 (3 marks) For students that slept less than 6 hours a night on average during April, list the grades for all assignments they completed during this time.

Task 3 [3 marks]

Insert (1 mark) Write an INSERT command to insert a new unit into the Unit table. The unit is called Advanced Database Management, with the code IFB801 and it will be offered in Semester 1 next year (2019).

Delete (1 marks) Write a DELETE command to remove all rows from the phone number table where the phone number starts with 02.

Update (1 mark) Write an UPDATE comment to change the address of all students with the last name Smith who live at 180 Zelda Street, Linkburb to 72 Evergreen Terrace, Springfield.

Task 4 [3 marks]

Create Index (1 mark) Currently the database only contains a small number of records. However, the data contained within it is expected to grow significantly in the future. Creating indexes on commonly searched columns is a way performance issues can be minimized.

Write a command to create an index on assignmentName of the assignment table.

Create view 2 marks

Write a command to create a view to list the firstname, surname and student ID of any students that havent enrolled in any units.

Task 5 [2 marks]

Pulse Learning have two employees, Nikki and Jake, to work with the MySQL database. Working as MySQL database administrator, provide the commands required to grant or revoke access so the following security requirements are met:

A. User Nikki must be able to add records to the STUDENT table (0.5 Marks)

B. User Nikki must be able to remove records from the STUDENT table (0.5 Marks)

C. User Jake is no longer allowed to add data to the STUDENT table (0.5 Marks)

D. User Jake is no longer allowed to delete records from the STUDENT table (0.5 Marks)

Assume usernames of employees Nikki and Jake are nikki and jake respectively.
