ensures that the input and output data flows of the parent data flow diagram (DFD) are maintained on the child data flow diagram (DFD) Deciding whether to explode a process further or determine that it is a functional primitive is a matter of experience, judgment, and interaction with programmers who must translate the logical design into code.

(T/F) A data flow diagram (DFD) shows how data moves through an information system but does not show program logic or processing steps. A set of DFDs provides a logical model that shows what the system does, not how it does it. True False

What is Data Flow Diagram? Also known as DFD, Data flow diagrams are used to graphically represent the flow of data in a business information system. DFD describes the processes that are involved in a system to transfer data from the input to the file storage and reports generation.

July 1, 2021 - This tutorial focuses on the definition of the data flow diagram (DFD), levels of the DFD, and its different types. Before starting with DFD, lets first study about a process models. What is a Process Model? A process model is used to describe system activities and the flow of data among them.

• Spontaneous generation - refers to a process in a data flow diagram that has no inputs. (Note this is not desirable when you construct a DFD. A process must have inputs and outputs) •

Spontaneous generation- when a process produces output but has no input data flow. Black hole- when a process has input, but produces no output. Gray hole- when a process has at least one input and output, but the input is obviously not enough to generate the output shown.

Data flow diagrams

Three data flow and process combinations that you must avoid: • Spontaneous generation. The APPLY INSURANCE PREMIUM process, for instance, produces output, but has no input data flow. Because it has no input, the process is called a spontaneous generation process.
