Draw a Context Diagram and a Level 0 Diagram for the following system: Starrs Financial Services Ltd. (Starrs) offers an interesting service to its clients. Using a client's date, time, and place of birth, Starrs draws up an astrological profile advising when and how to invest money. Clients telephone their orders directly to the Starrs sales clerk. Each order includes a client's name, address, date, time and place of birth, and credit card number. The sale clerk checks the credit card number against a stop list generated by the credit card companies. When an order is accepted, it is split into order details (name, address and credit card number) and personal details (name, address. date. time and place of birth). The sales clerk passes the personal details on to the company astrologer, and places the order details in an order file.

The astrologer uses the client's personal details and matches them with information from the financial press to produce an astrological profile. This profile is returned to the sales clerk, who posts it out to the client. Once a day, the sales clerk takes orders from the orders file, and produces bulk claims that are sent out to the credit card companies. Every month, the credit card companies send statements to Starrs indicating the amount of money that has been transferred to Starrs bank account.
