Research On Enterprise Application Integration Based On Web Services Discovery

With the fast development of informationization process in enterprises, more and more enterprises start to construct the architecture of enterprise application integration that suits their own actual profession. They hope the growing needs of business can be satisfied by the system application integration, which can also eliminate the great information gap for supporting communication exists on the road of enterprise development, raise the efficiency of service and improve the compatibility of responding the changes of market demand, and then reach the final aim of enhancing comprehensive strength and competition ability.This paper analyzes the merits and shortcomings between the traditional EAI and the new EAI that based on Web service, discovers the prominent problems the enterprise integration facing currently, and introduces the technology of Web service discovery to solve the problem of low discovery efficiency and the incomplete discovery mechanism among the enterprise application integrated architecture. By comparing many kinds of Web service discovery technology the paper builds a novel Web service discovery model based on multilayer and screening. After experimental verification, the method has higher recall and precision. Moreover, the paper proposes an improved frame of EAI that based on the new kind of Web service discovery model and Web service discovery technology and expresses the whole structure and working mechanism of various parts in details. Finally, combining with the prominent problems occurred in tobacco enterprises application integration, such as high coupling, compatibility, low reusing, a frame of EAI based on SOA is built, which meets the special demand and is feasible after evaluating by practical cases.
