This behavior is analyzed and represented as a series of events that can occur in one or more possible states. Hereby 'each diagram usually represents objects of a single class and track the different states of its objects through the system'. State diagrams can be used to graphically represent. This was introduced by and in their 1949 book 'The Mathematical Theory of Communication'. Another source is in his 1967 book 'Sequential Machines and Automata Theory'. Another possible representation is the.

Directed graph [ ]. Diagram showing how Harel's Statecharts contributed to object-oriented methods and notation Harel statecharts, invented by computer scientist, are gaining widespread usage since a variant has become part of the (UML).

[ ] The diagram type allows the modeling of,, and activities as part of a state. Classic state diagrams require the creation of distinct nodes for every valid combination of parameters that define the state. This can lead to a very large number of nodes and transitions between nodes for all but the simplest of systems (). This complexity reduces the readability of the state diagram.

With Harel statecharts it is possible to model multiple cross-functional state diagrams within the statechart. Each of these cross-functional state machines can transition internally without affecting the other state machines in the statechart.

The current state of each cross-functional state machine in the statechart defines the state of the system. The Harel statechart is equivalent to a state diagram but it improves the readability of the resulting diagram. Alternative semantics [ ] There are other sets of semantics available to represent state diagrams. For example, there are tools for modeling and designing logic for embedded controllers. These diagrams, like Harel's original state machines, support hierarchically nested states, orthogonal regions, state actions, and transition actions. State diagrams versus flowcharts [ ] Newcomers to the state machine formalism often confuse with.

State Transition Diagram (STD) saja sudah cukup (bandingkan dengan UML yang harus mencakup 9 deliverables) Tapi kalau anda menggunakan bahasa pemrograman yang sifat dasarnya sudah object-oriented seperti PHP, ASP dan semua web-based programming, berarti anda menggunakan OOAD dan harus menggunakan UML untuk perancangannya.

The figure below shows a comparison of a with a flowchart. A state machine (panel (a)) performs actions in response to explicit events. In contrast, the flowchart (panel (b)) does not need explicit events but rather transitions from node to node in its graph automatically upon completion of activities. Nodes of flowcharts are edges in the induced graph of states. The reason is that each node in a flowchart represents a program command. A program command is an action to be executed.
