Draw an activity diagram that models the reimbursement process described below. Use one swimlane for each of the three actors in the process.
The travel reimbursement process for employees of West Nile Valley University involves three different actors: the employee, the employee’s departmental secretary, and the treasurer’s office. First, the employee has to gather and prepare all of the receipts the university requires for reimbursement. At the same time, she completes the official reimbursement form. She then submits both the receipts and the form to the departmental secretary. If something on the form is incorrect, the secretary returns the form to the employee for correction. If the form is correct, the secretary prepares a form required by the university. That form is then submitted to the treasurer’s office. The treasurer’s office then enters the amount to be reimbursed into the university’s system. The employee is then asked to review the reimbursement amounts. If the amount shown is not correct, the employee must indicate that this is the case. If the amount shown is correct, then the treasurer’s office sends the reimbursement to the employee’s bank, completing the process.

Draw a use case diagram for the following situation (state any assumptions you believe you have to make in order to develop a complete diagram). Then convert the use case diagram into a sequence diagram
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, an asking price, and a condition as well as open-ended comments. Stillwater works with many different individuals, called clients, who sell items to and buy items from the store. Some clients only sell items to Stillwater, some only buy items, and others both sell and buy. A client is identified by a client number and is also described by a client name and client address. When Stillwater sells an item in stock to a client, the owners want to record the commission paid, the actual selling price, the sales tax (tax of zero indicates a tax-exempt sale), and the date the item sold. When Stillwater buys an item from a client, the owners want to record the purchase cost, the purchase date, and the condition of the item at the time of purchase.
