Fordley Car Park is open between 7am and 9pm every day. They charge £2.30 per hour with a minimum fee of one hour and a £2 overnight charge for stays between 9pm and 7.30am. Payments are made at the end of a visit. The car park is also used by resident and business permit holders on the basis of annually renewable membership. All new memberships are registered via the Fordley Car Park website or by completing a form which can be picked up from the car park attendant. Recently Fordley has invested in a paperless attended smart parking system that scans car registration numbers as cars drive through the entrance gate. To ensure that a reading has been captured, the gates only open when a valid registration is read.

Computer Science A study conducted by Netflix’s consumer relations department has revealed that customers are more likely to review horror and thriller movies during certain months of the year. To discourage seasonal variations in these movie ratings, Netflix has called for your help to analyze horror and thriller movie rating counts over the past 15 years. Your query should display each month of the year (name of the month not the number) and the total number of ratings given during that month. A third column titled “Promotion Recommendation” determines whether a promotion should be applied to increase the number of ratings given during that month. If a month has less than 2200 ratings the final column should display ‘10% discount promotion’, if between 2201 and 4500 then display ‘5% discount promotion’, and if more than 4500 ratings then output ‘No Promotion’. Order your results by months. Do not hardcode the current date. ORALCE CODE PLEASE.
