Read the scenario below and prepare three analysis DFDs: Context, Level 0, Level 1.

You are part of a systems analysis team looking at the enrollment system of a nearby college. The team is working to determine requirements for a new system. You are working with users of the current system to document the current process students use to register for classes. Preliminary interviews reveal that students request courses to be added to their schedule. The system checks to see if students have the proper prerequisites. The system checks to see if the requested class is full. A class roster is sent to the faculty teaching the class. A class schedule is sent to each student. You must discover other details about the registration process by talking with students. Then, draw a Context Level data flow diagram showing the boundary of the system under study. "Explode" your Context DFD to show increasing levels of detail: Level 0 diagram, Level 1 diagram. Draw your DFD's using any appropriate graphics software.

PowerPoint Presentation: Slide 1 for the Context DFD; Slide 2 for the Level 0 DFD; Slide 3 for a Level 1 DFD.
