module 10 An unusual problem has occurred for a small multinational company: People are getting confused about dates in internal memos, purchase orders, and email. When the company’s database was originally designed, the designer was not aware that the format for dates in Canada and Mexico was different from the format used in the United States. For example, in Canada and Mexico, the notation 7/1/19 indicates January 7, 2019, whereas in the United States the same notation indicates July 1, 2019. Although it seems like a small point, the date confusion has resulted in several order cancellations. How would you fix this issue in the database?
