Question

Decision Table and DFD fragment (30 marks);;Scenario;The discount given to the car insurance customer is determined from three different conditions. Firstly, whether the customer is Young (18-24), or Mature (25 or older). Secondly, the customer?s home address is considered to be Low (L), Medium (M), or High (H) risk. Finally, whether the customer has made any claims within the last two years (Y or N).;A mature person gets a 20% discount while a young person gets no discount for their age. Someone who has a low risk address gets a 10% discount whereas a person with a medium risk address gets a 7% discount, and those with high risk addresses get no discount for their address. Those who have made no claims in the last two years receive a 5% discount. All discounts are cumulative. In other words the discounts based on age, location and previous claims are added together. So for example, a mature person living at a low risk address who has made no claims in the last 2 years would receive a 35% discount.;1.;Draw a decision table that shows all possible rules for the above scenario.
