Web Services Based Information System Integration Research And Application

With the development of information technology, computer technology isincreasingly subject to the attention of businesses and organizations to control andmanage the process. For large enterprises or industries, the construction ofinformation systems is difficult to complete. It is often very different because ofdifferent business backgrounds, different periods, and different developing systemteams. Therefore， enterprises need the introduction of new platforms andtechnologies to solve the problem of decentralized management application unit,unified application software platform and so on. Through the integration of variouscategories of heterogeneous, isolated applications and resources, information systemintegration based on web service make an interconnection integrated platform to solvethe problem of connection and collaboration between applications.This paper studied the web service, its key technology (HTTP/XML/SOAP) andportal technology, including the unified portal, the general role authorization based onrole, general style interface based on role and general content based on role. Amongthem: the establishment of a unified portal is a necessary means to improve thefriendliness of the system; the general role authorization based on role, style interfaceand interface content based on role is one of the key information system integration.Through establish unified information portal of integrated enterprise serviceplatform, support the unified user management, provide a single system entrance forall types of users inside and outside the enterprise.The unified portal optimization ofportal-based information technology business work environment, support theintegration of different businesses, services and features, provide a customized, simpleand efficient working environment and user interface for all types of users. Generalrole permissions by role can be a set of permissions disposable give the operator,unified and standardized management. Role-based interface style provides users with a key switch interface style function, allows the users to customize the interface style.The user can configure the system style according to personal habits and preferencesin the personal settings after log on to the system. Role-based interface content mainlybe customized to the specific content of the information and services module. Forexample, users can custom-do to receive different business modules work notice. Thesystem administrator can define different roles matching different menus.Through the system construction of integrated service platform for thedevelopment of enterprises, test the function of general role authorization based onrole, style interface and interface content based on role, verify the design scheme ofthe unified portal. From the results, it can basically meet the system construction ofthe enterprise integrated service platform business needs, to enhance friendly ofplatform, improve the work efficiency of users. In the system development,deployment, maintenance, improve development efficiency, quickly adapt to thechanging needs, easy maintenances, reduce the difficulty of deployment.
