Suppose you were asked to design an on-line university. For this homework assignment, let's try reverse engineering our WebTycho classroom and expressing the result as a DFD. Here is my actual view of our class environment. For your Context Diagram (Level 0) call the process ... Perform On-Line University Functions. Then decompose into two more levels (Levels 1 and 2). The first level (Level 1), after your Context Diagram will be the top level functional decomposition of the system into its basic functions. For the next level (Level 2), only decompose one of the processes from Level 1. Your answer will consist of 3 PowerPoint slides - one for the Context, one for Level 1, and one for the decomposition of one of the Level 1 processes into Level 2.
Perform functional decomposition and build a Data Flow Diagram (DFD).
