The diagram shows only the major information flows between the system and the
external parties that interact with the system
Outside sources/systems/agents - answer You can tell something or someone is an
outside source because you do not know details about how the data you receive was
created
Decomposition - answer When you take the processes shown on a DFD and divide
each into more detailed (sub)processes, this is referred to as decomposition
Balancing - answerWhen you balance a DFD it means you preserve the inputs and
outputs of a parent DFD at the next level of decomposition
Flowcharts - answerFlowcharts focus on the physical aspects of information flows, files,
sources, destinations and processes
Systems flowcharts - answerThey show the entire system configuration, including the
data inputs, data outputs, and processes of a system, and the relationships between

checks, invoices, ledgers, journals, and reports)
,Input/Output symbol (Paralellogram) - answerThe Input/Output symbol is typically used

ending point of the process represented on a flowchart.
It is also used to display system entry or exit of data
On-Page Connector (Small Circle) - answerOn-page connectors tell the user where to
go next when the flow continues on the same page
Off Page Connector (Weird Upside Down Triangle Like Shape) - answerOff page
connectors are used to connect multiple pages of a document flowchart.
Shown within the off page connector symbol is the page number that the flow continues
to (or from which the flow came) and a connector number
Annotation - answerThis symbol is used to include important supplementary information
or explanations that are difficult to describe graphically within the flowchart itself
Decision points (Diamond Shape) - answerA decision symbol would display the
decision, and a description of the decision would appear in the symbol (e.g. "Is the
document complete?"). Two labeled flow lines would exit from the decision symbol to
illustrate the indicated course of action
