Research And Application On .NET Component Composition Technology Based On DSSA And WF

Nowadays,software reuse has been deemed as an efficient solution of improving the software development efficiency and software product quality in software development.Software reuse is greatly promoted by the transformation from structured programming language to object-oriented programming language.However,it does not merely dependent on programming language alone.The technology of software architecture and software component provides important ideas for larger scale software reuse.Combining the technology of software component and software architecture,the software development method of component development plus component composition based on architecture becomes very popular.At the same time,domain engineering provides supports for component requirement in special domain and the technology of component composition has become the key of software development based on components.On the other hand,.NET has become the main technology of present software development.Accompanying the publication of new.NET Framework as well as development tools,more and more products are realized by.NET.The component technology of.NET is gradually replacing the previous component standard of Microsoft.Based on such background,this paper studies on both theory and practice aspects of the application of component composition technology of.NET combining the technology of.NET component and workflow in special fields and puts forward a component composition model based on.NET.In theory,this paper firstly studies the technology of software architecture, software reuse and software component.Furthermore,this paper mainly studies the technology of component composition based on the technology of.NET component and the application framework based on.NET.Meanwhile,in order to coping with the change of business process of application system and the flexibility of the development of component as well as it composition,this paper introduces the technology of workflow of Microsoft and analyzes its implementation principle.In practice,this paper puts forward a model of.net component composition named.NET-CCM combining the technology of.NET component,workflow and reflection technology in.NET.This paper also proposes the description of.NET component and development standard based on this model,and then,it illustrates the method of component composition and running mode of component.After that,it analyzes the composition characteristics of.NET-CCM and provides ideas for settling the problems maybe confronted in the development of component and the process of composition.Finally,combining the technology of windows smart-client and ClickOnce deployment,it applies.NET-CCM into the working platform system of court information intelligence and verifies the practicability of.NET-CCM.
