Document Summary

Which of the following systems flowcharting symbols descriptions is incorrect: tape, on-page connector, start/stop, paper file. Using good data flow diagram construction techniques draw a diagram to explode bubble 3. 0 to its next lower level. Diagram 3. 0 should contain three processes, appropriately numbered, and should contain the following data flows in addition to those in the level 0 diagram (see note): Flow h runs from the first process to the second. Flow i runs from the first process to the third. Flows j and k run from the second process to the third. Note: assume that the flows shown in the level 0 diagram affect diagram 3. 0 as follows: Flow d runs to the first process in diagram 3. 0. Flow b runs from the third process in diagram 3. 0. The data flow running from the data store runs to the second process in diagram 3. 0: figure tb-4. 3 shows a context diagram of a cash sales system.
