37 In A Data Flow Diagram (dfd), A Spontaneous Generation Process Is A Process That Has _____.

Flow chart diagrams can be useful for describing programming logic or understanding a single sequence of process activities. It is important to recognize, however, that DFDs are not flow charts. Flow charts often show both processing steps and data "transfer" steps (e.g., steps that do not "process" data); DFDs only show "essential" processing. In a data flow diagram (DFD), a spontaneous generation process is a process that has _____. • At least one input and one output, but the input obviously is insufficient to generate the output shown • No input • No output • At least one output and one input, but the output obviously is insufficient to generate the input shown

In a data flow diagram (DFD), a process symbol can have only one outgoing data flow. RULE 1: A process cannot produce an output data flow without at least one input data flow (Spontaneous Generation). RULE 2: A process cannot receive input without producing an output (Black Hole). RULE 3: A process cannot generate an output for which the sum of the input data types is insufficient (Grey Hole). RULE 4: Each process in always "running" and ready to accept data.
