Business Case for your ERD

A-TECH is an automotive service and repair company that receives a range of customer requests which include: regular vehicle servicing, repairs, performance modifications and Road Worthy Certificate inspections.

A-TECH employs mechanics (called Technicians) who are able to carry out a broad range of automotive activities for the company. Depending on the type of a customer request, it can completed by either one or several of the technicians at a time, however each technician can only be assigned to one request at a time.

A customer may make one or more requests (‘Job’) when they call A-TECH, and details about the customer and the type of requests (‘Jobs’) need to be tracked. Requests are identified by a RequestID field.

Also A-TECH needs to know the details of the technician who completed a request. Upon completion of a request, the customer receives an invoice that details the work done and the amount that must be paid. A-TECH needs to track all the invoices sent to customers and ensure payment for completed requests is received.

Part B

  1. Create a new database named ‘your student ID’ (eg: ZHAND1701) and save it into your studentfolder.
  2. Design a table called ‘Customer’ as below via the ‘Table Design’ button:
  3. Design another table called ‘Invoice’ as below:
  4. Enter these records into the ‘Customer’ table:
  5. Enter these records into the ‘Invoice’ table:
  6. Create an appropriate relationship between the 2 tables and enforce referential integrity.

Create a Form

  1. Create a new form, ‘Columnar style’ based on the ‘Invoice’ table and include all the fields from the Invoice table. Name the form Invoice
  2. Modify the look of the form and place a SIMPLE and CLEAR image of a car being repaired (find this image from an online search) in the header section of the form. Add a company name to your form. Add your full name and student ID in the footer section of the form.
  3. Change the background colour of all sections in the ‘Property Sheet section of the form.

Add field

Create Queries

Create these queries to answer the questions below:

  1. List all the customers who live in area ‘4216’ and include all the fields. Save the query as ‘Customer Area’.
  2. The total value of all discounted invoices for each customer, showing the field CustomerID, LName in the Customer table, and the fields Discounted Invoice Amount in the Invoice table. Save the query as ‘Invoice_Total’. Hint: you will need to use the a SUM Total.
