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.
