Data Flow Diagram Ref: http://yourdon.com/strucanalysis/index.html Bab 9 DFD
Elemen DFD • Process • Flow • Store • Terminator
Terminator • Typically, a terminator is a person or a group of people, for example, an outside organization or government agency, or a group or department that is within the same company or organization, but outside the control of the system being modeled
Guideline in constructing DFD • Choose meaningful names for processes, flows, stores, and terminators. • Number the processes. • Redraw the DFD as many times as necessary for esthetics. • Avoid overly complex DFDs. • Make sure the DFD is internally consistent and consistent with any associated DFDs.
Context Diagram atau DFD level 0 • Represents an entire system as a single process and highlights the interfaces between the system and the outside terminators
