If I were to design Ben & Jerry's data warehouse I would use several dimensions of information. The first dimension would consist of the company's products; ice cream, frozen yogurt or merchandise. The marketing department has to know which products are selling, if Ben & Jerry's didn't know that their T-shirts are selling out as soon as they hit the stores, then they wouldn't be able to take advantage of the opportunity to sell the shirts. The second dimension would consist of the different areas of sales; US, Canada, Mexico, or Europe.

If Ben & Jerry's could know when a season was coming to an end in a specific area, then they could forecast the need or the decline in need and speed up, or slow down distribution to those areas. The focus of the information is that it needs to be useful, and almost any information is useful. 2.

The Employee files primary key would be an employee number. The foreign keys for the Employee files would be; start date, wage, shift, employee address, paid time off, and...
