The TOPStay company has a large chain of hotels in many major cities globally, and is developing a new computer system to be used to support the rentals (or reservation) of hotel rooms online to clients. A client can reserve a hotel room online via TOPStay's website by giving the following details: city, check-in and check-out dates, number of adults and children, and number of rooms etc. Availability of the requested room(s) is checked against TOPStay's room reservation file. A list of available rooms is displayed (together with their corresponding price, type, room features and room photos) for client to choose. Next, client must give his/her personal/contact details such as date of birth, gender, address, passport name, and contact details including email address and phone number etc. Payment details from client such as credit card number, bank issuing the credit card, expiry date and name of credit card holder etc. must then be entered by the client. TOPStay will then contact the bank of client's credit card for credit approval. If the bank of the client's credit card gives the credit card authorization, a confirmation email together with the e-room voucher will be emailed to the client, otherwise the transaction is cancelled automatically. From the above description, draw a diagram showing the flow of input information (and/or data) and output information (and/or data) to and from processes within this booking/reservation system and any external environmental elements that interact with this system. In your diagram, you must identify the following: a. processes inside this booking/reservation system, (15 marks) b. external environmental elements and data stores that interact with any of the processes identified in (a), (7 marks) c. input and output information (and/or data) to and from each of the processes, data stores and external environmental elements identified in (a), and (b) (18 marks) (Hint: there are two environmental elements that interact with this booking system, and six main processes in this booking system) The TOPStay company has a large chain of hotels in many major cities globally, and is developing a new computer system to be used to support the rentals (or reservation) of hotel rooms online to clients.
