Implement Of Traditional Database Resource's Integration In EAI

Traditional enterprises lacked technique to integrate different systems, so a greate deal of key information was isolated in independent systems. Many departments did same and redundant work, it reduced the enterprise's efficiency and increased the cost. Enterprise's business flow would relate to many application systems, it demanded those systems could cooperate with each others, but the disunity of interface and architecture made those systems become some "lonely information islands".Enterprise Application Integration uses middleware as bond to connect many kinds of enormous systems and application and data resource in enterprise, so some important systems like E-Commerce and ERP and database in enterprise could share and exchange data..The dissertation firstly gives a brief introduction of EA1 background knowledge and one EAI platform-- WebMethods Integration Platform, and then detailedly describes one material EAI project(NISSAN Co. EaI project-NCIC) including the requirement, system structure, realization and testing, gives material logic design and realization of a middleware (flow service) that integrates the traditional database resource in enterprise.
