Research On Distributed Application Framework Based On Component Technique

With the complexity and requirement of software systems dramatically increasing,the software development meets great challenges and software crisis as a tardiness crisis still continues. So how to improve both efficiency and quality of software becomes a hotspot. Component-based Software technique is a mainstream in software reuse technique. As a big granularity component,framework provides base and context for the installing of component,which aims to resolve these challenges and to improve the efficiency and quality of software development. Having studied some latest conclusions and cases of software component technique and framework technique,this paper focuses on a distributed application framework based on component technique (CDAF). The structure and integration technique of CDAF are discussed as well.Now,much research of framework technique emphasizes on catholicity and currency,which makes stress on reuse of coding. It's still unusual to study or apply framework technique in some specific domains. This paper studies water quality monitor and manage domain,and based on CDAF,brings forward the application framework of WQMMS. Then,this paper discusses some typical problems and techniques in implementation of the issue.Finally,based on the framework of WQMMS,this paper presents a model of water quality forecasting system and a fulfilling process of the computing component of water quality forecasting.
