Assessment Scenario
You are working for a company called Maximum Velocity Cars as a Junior IT technician. Maximum Velocity
Cars is a car rental company whose Headquarters is based on Queen Street, Auckland, New Zealand. The
company opens from 6 am until 10 pm every day and has twenty-eight employees working on a shift basis
to cater for customers during opening hours.
The owner of the company, Mr Archer has asked you to create a Database to help his company keep track of
all the cars that are available to rent or are rented. He would also like the destination to be included so pick
up of cars can be arranged at noncompany drop-off points.
Your task is to create a database file by using the following information:
• CarFleet Table:
o CarID (AutoNumber)
o CarManufacturer
o CarModel
o CarBodyStle
o CarFuelType
o CarTransmission
o CarReleaseYear
o CarNumberofSeats
o CarColour
o CarLicensePlate
o CarRentalPrice

• Company Table:
o CompanyID
o CompanyBranchName
o CompanyLocation
o CompanyPhone
o CompanyEmail

• Rental Table:
o RentalID
o RentalCustomerID
o RentalCarID
o RentalPickupID
o RentalDays
o RentalTotalCost

• Customer Table:
o CustomerID
o CustomerFirstName
o CustomerLastName
o CustomerPhone
o CustomerEmail
o CustomerDrivingLicense
o CustomerPassport (If international)
o CustomerNextofKin
o CustomerNextofKinContactNumber © NZSE – (NZDITTS5) IT504 Web Design and Database Application (Assessment 2) v2.1 Page 4 of 17

Note: Take screenshots to show the various steps taken to produce the final database application and

alphabets, and special characters. Additionally, suggest another method of securing the
database.(LO5) (5 Marks)
11. Create queries:
a. Use the SELECT SQL statement to query data from different COLUMNS (RentalCarID,
RentalCustomerID and RentalDays) but from the same TABLE (Rental Table) (LO5) (2 marks)
b. Use the WHERE SQL clause to filter records using a condition (CarFuelType is petrol). (LO5)
(2 marks)
c. Use the NOT SQL operator to create a query to filter the date (CarReleaseYear) based on a
certain condition (the condition is up to the student). (LO5) (2 marks)
d. Use the AND SQL operator to create a query to filter the date (CarReleaseYear) based on a
certain condition (the condition is up to the student). (LO5) (2 marks)
e. Use the ORDER BY SQL keyword to sort the result-set for CustomerLastName in ascending
order. (LO5) (2 marks)
f. Use the MIN() SQL function to return the smallest value from the RentalTotalCost column.
(LO5) (2 marks)

Note: Check the marking rubric on pages 8-14 for the mark allocation and guidelines to ensure you gain
optimum marks.
