The Study On Web Services Component Library

In recent years, it has been already increasingly important that Software Reusewhich is used in the software industrial circle, it is considered as production efficiencyand way with feasible reality of quality to solve the crisis of the software , improve thesoftware, and of different new technologies to develop into Software Reuse and spendbringing new market and demand, especially realized " the software is served " thedevelopment of Web Services technology of the thought brings the new managementdemand. The software development based on component is the core of Software Reuse,and the component library system is as the system supporting the component to manageand maintain, must become the focus paid close attention by each side of softwareindustry naturally.This paper is based on component library technology and Web Services technology,has put forward the basic frame of two kinds of technology combining Web Servicescomponent library system, have studied the key technology of this system: description,save, management of systematic system structure, the security of the system and WebServices component. Web Services component library system has solved such problemsas management of component resources of Web Services and operation between thecomponent libraries.Web Services is a kind of outstanding distributed package technology, the librarysystem of component based on Web Services has good operation, platformindependence and elasticity. The component based on XML describes the characteristicof transmitting the data that have fully utilized XML mark to be with good languagestore the structure, expansibility, high structurization, convenient network, have solvedthe difficulty of component resource-sharing fundamentally. In addition, Web Servicescomponent library system can manage this kind of component resource of Web Services,raises the efficiency of Software Reuse.This paper has analyzed Web Services technology, component library technologyand combine possibility, proposed Web Services services model and system structureafter combining according to component library serve model and Web Services servemodel, studied the key technology which realizes this system in detail: the use of XML todescribe Web Services component, the XML file mapping to database, component savingand outputing, Web Services component systematic security and realized some practicaljob of Web Services component library system.
