I just need a level zero data flow diagram.

This assignment examines two documentation tools: data flow diagrams and flowcharts. Based on the following narrative description, create a context diagram and a Level 0 DFD. The Ames community college requires that each student complete a registration request form and mail or deliver it to the registrar's office. A clerk enters the request into the system. First, the system retrieves previous fees information in the accounts receivable file and checks whether fees are owed from the previous quarter. Next, for each course, the system checks the student information in the student record file and the course information in the course file to ensure that he or she has completed the course prerequisites. Then, the system checks the class availability using the class list file. If the class is available, the system then updates both the class list file and the student record file (i.e., registering the student to the course). The report back to the student shows the result of registration processing. If the student owes fees, a fees notice (i.e., bill) is sent to the student, and the registration is rejected. If prerequisites for a course are not fulfilled, a prerequisite notice is sent to the student, and that course is not registered. If the class is full, the student request is annotated with 'course closed,' and a course closed notice is sent to the student. If a student is accepted into the class, the course number, day, time, and room are printed in a student acceptance notice form, and the form is sent to the students later. Course enrollment reports are prepared and send to the instructors. In addition, student fees and total tuition are computed, and course enrollment reports are prepared. The course enrollment reports are then forwarded to the Provost Office and to the College President. This assignment examines two documentation tools: data flow diagrams and flowcharts.
