Knowledge Portal Construction and Resources Integration for a Large Scale Hydropower Dam

摘要

Based on the research project entitled 'Data Collection and Decision Support System for Hydropower Dam Construction' sponsored by the National Development and Reform Commission of China, this paper puts forward a multilayer architecture and a support system for the knowledge portal utilizing web services and J2EE while offering a method for integrating existing resources. The purpose for this system is to help the China Gezhouba Group Corporation (CGGC) manage the construction of a large-scale hydro-power dam. Through the interoperability in distributed environment, software integration technology and heterogeneous system integration, the interoperability of heterogeneous systems is realized by the enterprise application integration (EAI). In this project, an open and unified integration environment is provided by the analytic system (AS), making it possible for all kinds of software resources to be made readily accessible.
