For Case , you begin by thinking through the Student Registration System at Trident University to identify all external data sources (students, instructors, and student records, and be creative with more) and destinations as level "0" diagram.
During that process, you identify the entities, the name and content of the data flows, and the direction of the data flows. If you do that carefully, you will do a good job of fact-finding and should have no difficulty drawing the context diagram.
Draw an FDD of the portal system website for Trident University. Your FDD must consist of 3 levels. Write your assumptions, if any.
Draw a context diagram and a diagram 0 DFD that represents the registration system at your school or an imaginary school.
Next, you draw a Level 1 DFD exploding the students' record external entity (agent) and decompose it into processes, data stores, and data flows, using the symbols in Figure 2-10.
To help you answer Case question #2, keep in mind that the first step in constructing a set of DFDs is to draw a context diagram with the following DFD symbols to represent external entities, processes, data stores, and data flow directions as shown in Figure 2-10.
Your paper will be evaluated on the following criteria:
Diagram pictures and analysis to the questions must be written in 2-3 pages in MS Word, excluding cover and reference pages. Logical FDD and DFD should be copied from yEd or other design software and pasted in Word.
