This paper is set focus on the research of the component composition technology based on the software arthitecture.

Twelve appraise targets were put forward to evaluate schemes of technique assembly by means of measuring and analysing.

Global digital control system for pork safetyly production based on component technology;

Study on enterprise application integration facing manufacturing based on component technology;

Feasibility study on development of digital valley by component technology;

Design and realization of application server for social insurance system based on COM technology;

Desien and Implement of ERP Svstem Bases on COM Technology;

The Development of GIS Based on COM Technology--Make An Example of the Development of the Underwater Resource Spatial Analyse System;

Research and Practice of Modeling ERP System Based on Component Technique;

On the basis of brief introduction to the characteristics of ComGIS(Components Geo-graphic Information Systems) platform,the technology and method in designing GIS application platform with component technique for short circuit computing is put forward and the structural model of ComGIS-based short circuit calculation system is framed.

Traditional software development method cant meet the need of the large transportation software system development, while component technique can solve the problem that traditional software development method faced.
