網路醫學資訊系統之可擴充性與容錯機制

Abstract

本計畫「網路醫學資訊系統」讓醫療服 務得以藉由無遠弗屆的網路系統遍佈到世 界各地，來協助診療的進行。換句話說， 這就是「網路醫院」的具體實現。而在實 作上，我們採用分散式物件技術來架構網 路醫學資訊系統，除了能增加系統服務效 率之外，也將有助於系統的擴充與維護。 我們以Microsoft 的DCOM 技術為基礎， 在系統的實作過程中進一步探討分散式物 件在寬頻網路上的各項議題，如服務效 率、系統可靠度、容錯機制等等。

This project, a network medical information system will make medical treatment services ubiquitous through the widely-spread network systems in the world. In other word, this is the concrete realization of a “networked hospital”. We are going to build the network medical information system by the progressing distributed object technology that will increase system efficiency and be of great help in system extensibility and maintenance. Our implementation is based on the Microsoft DCOM technology. It is expected that there will be many research issues to be discussed during the development of a distributed object system over the broadband network, such as service efficiency, system reliability, and fault tolerance mechanisms.
