Introduction

Some areas of the software can be in a state transition diagram and state transition table showing the way out. Conversion software to change its status. When a when a condition occurs between states will make the appropriate conversion. Determination condition is caused by data entry. Data can take many forms, such as.

---signal;

---command;

---news;

--- Token, mark;

--- Character, word;

---recording.

This standard describes a minimum set of software for the state transitions of interpersonal communication concepts and symbols.

This standard.

a) define the nature of the state transition of software;

b) defines the state transition notation elements;

c) defines the state transition element set.

information Technology Interpersonal communication software indicates state transitions

1 Scope

This standard defines the concepts of charts and symbols can help indicate software functionality and conversion and can improve interpersonal communication. This standard covers the software requirements analysis and design phase of development, communication and review.

This standard is effective in the following areas of software.

--- Interactive Software (description and conversion functions represented on the screen);

--- Data communications software (described communication protocol and the corresponding action);

--- Language/command (described syntax).

2 Terms and definitions

The following terms and definitions apply to this document.

State state

Software is a unique value in a certain stage of its progress in the implementation process of representation. The state should have a unique name as its logo, known as the "name of the state." 2.2 Conversion transition Change from one state to another or the same state. Conversion occurs when a certain condition is met. Action can take place along with the conversion. shape Ceremony, the conversion consists of the following three parts.

--- Point part;

--- Conditions section;

--- Action part.

Directed by the two states and part identifiers.

--- Previous state identifier (pointing to the previous state);

--- After a status identifier (pointing to the next state).

Part of the expression conditions and the action takes place between the state and change the conditions to be met. When different states or between the same change in the state sector when given a variety of transformations that the conditions should be mutually exclusive.

Part expressing action accomplished by software according to the conditions of operation. May be any processing operation, the operation may also be empty.
