Stillwater Antiques buys and sells one-of-a-kind antiques of all kinds (e.g., furniture, jewelry, china, and clothing). Each item is uniquely identified by an item number and is also characterized by a description, asking price, condition, and open-ended comments. Stillwater works with many clients who sell items to and/or buy items from the store. A client is identified by a client number and is also described by a client name and client address. When Stillwater sells an item to a client, the owner wants to record the actual selling price and date sold. When Stillwater buys an item from a client, the owner wants to record the purchase cost and condition at time of purchase.
