Task 1: The Finance team wants to calculate a VAT (8%) on the amount of the stay reservations in the database. However, the team wants to calculate the VAT after the discounts are applied on the prices. In addition, it is important to remember if there is no discount/offers, then the value is NULL in the TRAVELS table.

In addition, execute the procedure to account for NULL values and send the respective result to the team. The VAT value should be rounded to 2 decimals.

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.
