Use the following narrative to construct the Context Diagram for the Pinnacle Publishing sales and book tracking system
The purpose of the sales and book tracking system is to provide a single central repository of all information about sales leads, books in process, and books for sale. The Sales Department will enter new authors to the system as they gather leads from various sources. In response, the system can produce mailing labels for sending information to authors. As salespeople enter information on their phone calls, the system will generate recall lists to help the salespeople schedule their calls. Management wants to get a sales performance report from the system.
Once a salesperson sells a publishing contract to an author and the author sends in a manuscript, the Production Department will create a book record to track the book through the production process. Each book will be assigned a "shepherd" who will oversee the production process for that book. The system will provide the shepherd with a list of the status of each of his or her books each day. When the shepherd sees that a task has been finished for a book, the shepherd will assign another task and select the technician to complete that task. The system will communicate that assignment to the technician via e-mail.
Technicians will enter updated information to the system as they complete their tasks. The system will also output information daily from the database to a self-service web site where authors can check on the status of their books. As the book comes to press, production people will enter information about promotions being done, ISBN, and other information.
The Sales Department continues to work with authors who have submitted books to sell them various promotional options. The Production Department fulfills those options.
For books that are published, the system needs to pull sales information from several external e-commerce web sites. This information will be used by the Accounting Department to generate royalty reports to use to pay authors.
