Acme Corporation wants to automate the process of internal expense reimbursements. There are three steps in the process - employees filing expense reports for official expenses, manager approving the expense report, and finance department issuing a cheque for the amount claimed. a. Provide a design for all the tables that would be needed to capture the information, and the relationships between the tables. b. Provide a UI design for the front-end that allows employees to file expense reports, for managers to view expense reports waiting for their approval, and for finance manager to view pending expense reports. c. Enumerate the classes required (UML is optional) for handling all the transactions and control flow in the application.    More>>
