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.
