A: Make a list of 5 internal data (specific data points such as “first name” and “sales per day”) that the following companies would have in their database: Amazon.ca, Pharmaprix, and Concordia University. (different ones for each. They should not be ordinary ones, i.e. first name and last name!). B: For each one, write a brief logic that why you think it could be a useful one. i.e. for birth date, you can say they might use it to congrats and provide coupons.

Question

A: Make a list of 5 internal data (specific data points such as “first name” and “sales per day”) that the following companies would have in their database: Amazon.ca, Pharmaprix, and Concordia University. (different ones for each. They should not be ordinary ones, i.e. first name and last name!).

B: For each one, write a brief logic that why you think it could be a useful one. i.e. for birth date, you can say they might use it to congrats and provide coupons.

Hint: Name and sales per day are the two examples of distinct information, which a company might have in its internal database. Another piece of information might be, for example, email address, gender, price trends, and so on. I am asking for a list containing 5 of such information - not real or mock examples: i.e. John, $20, etc - for each of the four companies. This information could be stored by different methods, i.e. when you sign up or purchase products from Amazon, you provide Amazon several different kinds of information. The same might be once you want to pick up your prescribed medicine from the Pharmaprix. The goal of this assignment is to think of different types of information a company has.
