The ASM Method is a practical and scientifically well-founded systems engineering method that bridges the gap between the two ends of system development: . the human understanding and formulation of real-world problems (requirements capture by accurate high-level modeling at the level of abstraction determined by the given application domain)
Behavioral state machines can be used to model the behavior of individual entities (e.g., class instances), a subsystem, a package, or even an entire system. Protocol state machines are used to express usage protocols and can be used to specify the legal usage scenarios of classifiers, interfaces, and ports.
Web applications are software-intensive systems [5] and UML is among the efficient choice of languages for modeling them. Web software complexity of an application can be minimized using various UML tools. UML-based web engineering aims at offering a UML profile that matches the needs of web development better. The following are examples:
A state diagram for a door that can only be opened and closed. A state diagram is used in computer science and related fields to describe the behavior of systems. State diagrams require that the system is composed of a finite number of states. Sometimes, this is indeed the case, while at other times this is a reasonable abstraction.

State diagram for a turnstile A turnstile. An example of a simple mechanism that can be modeled by a state machine is a turnstile. [4] [5] A turnstile, used to control access to subways and amusement park rides, is a gate with three rotating arms at waist height, one across the entryway.
The state pattern is a behavioral software design pattern that allows an object to alter its behavior when its internal state changes. This pattern is close to the concept of finite-state machines . The state pattern can be interpreted as a strategy pattern , which is able to switch a strategy through invocations of methods defined in the ...
Now if the machine is in the state S 1 and receives an input of 0 (first column), the machine will transition to the state S 2. In the state diagram, the former is denoted by the arrow looping from S 1 to S 1 labeled with a 1, and the latter is denoted by the arrow from S 1 to S 2 labeled with a 0. This process can be described statistically ...
