Extension Analysis for Object-oriented Programming Technology

This article introduces the extension analysis for the object oriented programming technology,discusses the object matter element's “multi value",and presents the transformation conditions of the object matter element and the rules of decomposition and combination.The compatible and non comaptible problem in computer development is considered by man machine interface's DVI. At the same time,the concept of “replace prices" is presented.Taking the word processing software for example,extension analysis used in the optimization of object oriented programming works well.
