You have been requested to develop an online shopping mall with the following characteristics: The CEO of a company plans to build an online shopping mall. Main users of the online shopping mall are CEO, staff, and customers. All users must be registered to the online shopping mall. Customers can select items from the online shopping mall and store them into wish list. However, for items that are sold out, customers cannot add them in the wish list. Customers can remove items from the wish list. Customers can pay by credit or debit card. Once purchase has been made, the system sends receipt to customer’s registered email. Customers can send messages to staff using chat service in the shopping mall and Staff must reply to unread messages. Staff is responsible of refilling inventories of items being sold in the online shopping mall. Staff uploads or remove items sold in the online shopping mall as well. Staff can write / modify item information. Staff has access to customer personal/payment information to provide answers from customers. The system generates a daily summary report at 9 pm every business day and a monthly report at the end of each month. The report shows the information of company’s sale for a day or a month. The report contains each products name, number of items sold in a day. The monthly report is a summary of daily reports for a month. The daily and monthly reports are stored in the system so that the CEO looks at them any time. Design the software architectural model for the online shopping mall where the model is defined in terms of subsystems and their interactions. Each subsystem should be represented with objects supporting the subsystem. Define the communication styles between subsystems.
