The Queen Anne Curiosity Shop sells both antiques and current-production household items that complement or are useful with the antiques. For example, the store sells antique dining room tables and new tablecloths. The antiques are purchased from both individuals and wholesalers, and the new items are purchased from distributors. The store’s customers include individuals, owners of bed-and-breakfast operations, and local interior designers who work with both individuals and small businesses. The antiques are unique, although some multiple items, such as dining room chairs, may be available as a set (sets are never broken). The new items are not unique, and an item may be reordered if it is out of stock. New items are also available in various sizes and colors (for example, a particular style of tablecloth may be available in several sizes and in a variety of colors).
A. Create a sample list of purchased inventory items and vendors, and a second list of customers and sales. Your first list should include inventory data such as a description, manufacturer and model (if available), item cost, and vendor identification and contact data you think should be recorded. The second list should include customer data you think would be important to The Queen Anne Curiosity Shop, along with typical sales data.
B. Describe problems that are likely to occur when inserting, updating, and deleting data in these spreadsheets.
C. Attempt to combine the two lists you created in part A into a single list. What problems occur as you try to do this?
D. Split the spreadsheets you created in part A into tables such that each has only one theme. Create appropriate ID columns.
E. Explain how the tables in your answer to part D will eliminate the problems you identified in part B.
F. What is the relationship between the tables you created from the first spreadsheet and the tables you created from the second spreadsheet? If your set of tables does not already contain this relationship, how will you add it into your set of tables?
