for one of the following requirements: (1 point) a a Create a new receipt b Add data to the invoice c Add data to the product Create a function for one of the following requirements: (1 point) a Indicate the total amount for a certain receipt b Indicate the total amount for a certain invoice Create a trigger for one of the following requirements: (1 point) a Update the quantity and price for the product when it is imported For example, in the receipt “PN01”, enter the PEPSI product with the quantity of 10 and the price of 10,000, then increase the quantity of PEPSI by 10 in the Product table and update the new price to 10,000 b Update the quantity for the product when a sale is made For example, in a invoice “PB01” that sells a PEPSI product in quantity of 10, subtract this quantity of PEPSI from the Product table 14 Solution: Draw ERD model: Picture ERD model 15 Relational model: Picture Relational model 16 Create database, table and insert datas: Picture Create database and
