Question: A music store owner needs to have enough of the hottest CDs in stock so people who come to buy a particular CD won't be disappointed - and the store won't lose the profit. CDs that are not sold within a certain length of time go onto the sale table where they may have to be sold at cost, if they sell at all. The owner wants to design a decision support system to predict how many copies she should purchase and what information she will need.

Problem: List some of the considerations that would go into such a system as if you were the owner of the store and your business profits were at stake.

Can you help me! I am not actually sure how to answer the problem.
