Create a physical data flow child diagram for the following situation: The local running club holds meetings once a month, with informative speakers, door prizes like pre-paid entry fees for races, designer running gear, and so on, and sessions for special interest groups (people who want to coach, people who want to run marathons, those who want to get fit, and so on). A laptop computer is taken to the meetings and is used to add the names of new members to the group. The diagram represents an online process and is the child of Process 1, ADD NEW MEMBERS. The following tasks are included:
a. Key the new member information.
b. Validate the information. Errors are displayed on the screen.
c. When all the information is valid, a confirmation screen is displayed. The operator visually confirms that the data are correct and either accepts the transaction or cancels it.
d. Accepted transactions add new members to the MEMBERSHIP MASTER file, which is stored on the laptop hard drive.
e. Accepted transactions are written to a MEMBERSHIP JOURNAL file, which is stored on a second hard drive.
