Formal process flow diagrams are often called process maps, activity diagrams, or workflow diagrams. Historically, process analysts have used a wide variety of different diagramming notations to describe processes. This is not surprising when you consider all of the different groups that do process ...
The following three call flow diagrams are merged. The keyword "SipApp" is used to identify the lifeline that is going to be modeled in the state machine. These three call flows represent the behavior of a simple call blocking service with text notification. When a call is blocked the serv...
Top-down decomposition, also called leveling, is a technique used to show more detail in lower-level DFDs. Leveling is done by drawing a series of increasingly detailed diagrams until the desired degree of detail is reached. As shown in the Figure, DFD Leveling is first displaying the targeted...

The diagrams illustrate variations in house designs that are adapted to either cool or warmclimates, highlighting differences primarily in roof shape, window orientation, and insulation types. One of the most striking distinctions is seen in the design of the roofs. Houses in cool climates feature...
Context Diagram (Level 0): a general overview of a system is usually represented with a high-level DFD called a context diagram or Level 0 DFD. These diagrams are designed to be simple and straightforward overviews of a process or system, making them easily comprehensible to a broad audience...
Data Flow Diagrams The process model is a core diagram in structured analysis and design. Also called a data flow diagram (DFD), it shows the flow of information through a system. Each process transforms inputs into outputs. Flow lines represent data flowing between nodes including processes, ...
