State machine diagram is a kind of UML diagram that shows flow of control from state to state within single object. A state diagram is used to represent the condition of the system or part of the system at finite instances of time. 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 forms of state diagrams exist, which differ slightly and have different semantics STATE DIAGRAMS PATTERN DETECT EXAMPLE FINITE STATE MACHINES •STATE DIAGRAMS-STATE DIAGRAM EX.-BIT FLIPPER EX.-PATTERN DETECT EX.

Why State Machine Diagrams? State machine diagrams are usually applied to objects but can be applied to any element that has behavior to other entities such as: actors, use cases, methods, subsystems systems and etc. The best way to understand state diagrams is to look at some examples of state diagrams. Of course, you can use these diagrams for anything system or process that has various states – library books, a publishing process, even punishment and reward states for your kids. A transition from this state will show the first real state The final state of a state machine diagram is shown as concentric circles. State diagrams are also useful for describing how an object moves through various states within its lifetime. These UML diagrams are a combination of an activity diagram and sequence diagrams, where each individual activity is placed in its own frame, so it is easier to program. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. Because this example is simple, and contains no parallel actions or states, it wouldn’t make sense to use both types of diagrams. The initial state of a state machine diagram, known as an initial pseudo-state, is indicated with a solid circle. The first bar is often called a fork where a single transition splits into concurrent multiple transitions. This is achieved by drawing a state diagram, which shows the internal states and the transitions between them. The model defines a finite set of states and behaviors and how the system transitions from one state to another when certain conditions are true. You can construct your diagrams with drag and drop, save your work in cloud workspace, output and share your design via numerous formats such as PNG, JPG, SVG, PDF, etc. A flowchart illustrates processes that are executed in the system that change the state of objects.
