WebWhat is a data flow diagram? A data flow diagram (DFD) maps out the flow of information for any process or system. It uses defined symbols like rectangles, circles and arrows, … WebA logical DFD focuses on the business and business activities, while a physical DFD looks at how a system is implemented. So while any data flow diagram maps out the flow of information for a process or system, the logical diagram provides the “what” and the physical provides the “how.”. They are two different perspectives on the same ...

State diagrams require that the system described is composed of a finite number of states; sometimes, this is indeed the case, while at other times this is a reasonable abstraction. Many … See more State diagrams are used to give an abstract description of the behavior of a system. This behavior is analyzed and represented by a series of events that can occur in one or more possible states. Hereby "each … See more A classic form of state diagram for a finite automaton (FA) is a directed graph with the following elements (Q, Σ, Z, δ, q0, F): • Vertices … See more There are other sets of semantics available to represent state diagrams. For example, there are tools for modeling and designing logic for … See more An interesting extension is to allow arcs to flow from any number of states to any number of states. This only makes sense if the system is allowed to be in multiple states at once, which implies that an individual state only describes a condition or other partial … See more Harel statecharts, invented by computer scientist David Harel, are gaining widespread usage since a variant has become part of the See more Newcomers to the state machine formalism often confuse state diagrams with flowcharts.
