In a data flow diagram (DFD), a spontaneous generation process is a process that has _____. a. at least one input and one output, but the input obviously is insufficient to generate the output shown b. at least one output and one input, but the output obviously is insufficient to generate the input shown c. no input d. no output

Data Flow Diagrams (Cont.) Data flow symbol. Spontaneous generation (Process must act on input) Black holes. Gray holes. FIGURE . 5-6 . Examples of incorrect combinations of data flow and process symbols. APPLY INSURANCE PREMIUM has no input and is called a spontaneous generation process. CALCULATE GROSS PAY has no outputs and is called a black ...

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. • Black hole.

In data flow diagrams (DFDs), a process resembles a _____, where the inputs, outputs, and general functions of the process are known, but the underlying details are not shown. black box In a data flow diagram (DFD), a gray hole is a process that has _____.

Spontaneous generation, gray holes, and black holes ...

Similarly "Snail Mail" is put in my box. Memos, rosters, etc. are all buffered for me. So when modelling a real system you son't have to say that data in a data flow is in a queue. This is part of the DFD model. Data Flows The data flow diagram -- DFD is the central diagram used in information technology. A DFD is a circuit diagram of an ...

1. 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. 2.

Previous Post Previous In a data flow diagram (DFD),the Gane and Sarson symbol for an entity is a ____. Next Post Next In a data flow diagram (DFD),a spontaneous generation process is a process that has _____.

A DFD shows ____. a.how data are related b.what key fields are stored in the system c.how a system transforms input data into useful information d.what data is stored in the system , In a DFD, the Gane and Sarson symbol for a process is a ____., A spontaneous generation process is a process that has no ____., A black hole is a process that has no ____.

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 ...
