Once you have modified your database, you must then populate it with data using your insert into statements; however, you will need to modify your insert into statements for your product entity since it no longer has the unitprice attribute. after populating all of the other tables in your improved database, you will then need to populate the price_history entity by using insert into statements. use the previous unit price value with price valid from 1/1/2017 until 3/31/2017. then from 4/1/2017 until 5/20/2017, increase each unit price by 4% from the previous price. then from 5/21/2017 until 5/29/2017, increase each unit price by 5% from the previous price. then from 5/30/2017 until 7/07/2017 decrease each unit price by 10% from the previous price. then from 7/08/2017 until 11/25/2017, increase each unit price by 10% from the previous price. then from 11/26/2017 until 12/31/2018, increase each unit price by 4% from the previous price. populate your tables with the correct data.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
