Instructions:
This assignment, in two parts, is based on learning materials covered between Week 9 – Week 11 from the Hunt and ClemensText,andisrelatedtotheWeek10and11topic
Part A:
1. Download the Word document titled ‘Assignment 3 ERD Template’ and fill in your details.
2. Save this document as your ‘student ID’ (eg: ZHAND1701)
3. Prepare an Entity Relationship Diagram (ERD) in MS Visio (use Crow’s Foot Database Notation tool) or
Gliffy for the case below: The diagram must include:
• All entities from the business case. You MUST use this case (below).
• Correct relationships between the entities based on the business case
• Entity labels
• Primary keys
• Attributes based on the business case. (Be sure to use the correct symbols!).
Business Case for your ERD:
ZenaTech 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.
ZenaTech 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 be 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 ZenaTech, and details about the customer and the type of requests (‘Jobs’) need to be tracked. Requests are identified by a RequestID field.
Also ZenaTech 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. ZenaTech needs to track all the invoices sent to customers and ensure payment for completed requests is received.
4. You will need to copy the diagram using a screen shot PrintScrn or Snipping Tool into the Word document ‘student ID’ you completed earlier in point 2. Make sure the screen shot is complete, large andclearenoughtobe viewed.
