Final answer:
To draft Data Flow Diagrams for an existing system, a sequence of planning activities should be followed, starting with a table of entities and activities and culminating in detailed physical and logical diagrams.
Step-by-step explanation:
The question pertains to the steps involved in drafting Data Flow Diagrams (DFDs). The activities are presented out of order and need to be correctly sequenced for effective diagramming. The typical sequence for drafting would start with identifying the elements involved in the process which is done in Activity I: Prepare a table of entities and activities. This is followed by additional detail in Activity II: Prepare an annotated table of entities and activities, providing more information about the identified elements. Next, one would draw a Activity V: context diagram to establish the boundary and interfaces of the system. Subsequently, one would prepare a Activity IV: logical data flow diagram, representing the system processes and data flows abstractly. Finally, the student would create a Activity III: physical data flow diagram, which maps out the actual implementations and data stores. Utilizing a graphic organizer, such as Table 4.1, can facilitate this process.
