Data Flow Diagrams and Structure ChartData Flow Diagrams and Structure Chart

Based on the event table in deliverable 1, draw the DFD with Based on the event table in deliverable 1, draw the DFD with automation system boundary (refer Figure 10-2)automation system boundary (refer Figure 10-2)

Develop a high-level structure chart using transaction analysisDevelop a high-level structure chart using transaction analysis (refer Figure 10-10)(refer Figure 10-10)..

For one of the event in your event table in deliverable 1 you will For one of the event in your event table in deliverable 1 you will create a DFD fragment, exploded view of the DFD, and rearranged create a DFD fragment, exploded view of the DFD, and rearranged view of the DFD (refer Figures 10-11, 10-12, and 10-13).view of the DFD (refer Figures 10-11, 10-12, and 10-13).

Based on the rearranged view of the DFD, develop a first draft Based on the rearranged view of the DFD, develop a first draft of the structure chart using transform analysis (refer Figure 10-of the structure chart using transform analysis (refer Figure 10-14)14)
