Application Research Of Distributed Object Technology Based On CORBA

The network-based application model has transformed from Client/Server(C/S) into Browser/Server (B/S). Browser/Server model is the technical basisof e-business and gives a simple and practicable solution for e-businessapplication. At present, many aPplications adopt CGI. 1SAPI. ASP etc..These technologies have advantage of solving some simple problems, butthey can not solve complex problems. Otherwise, Web Server is ineffectiveand is not suitable for large distributed aPplication.CORBA(Common Object Request Broker Architecture) is industrycriterion, which had been brought up by Object Management Group in l990.Its basic principle is that different software modules are compatible with eachother by ORB soft-bus. So any application program or software system whichmeet with the criterion, can be aggretated into CORBA system. As a newobject-based distributed computing technology, CORBA supports a new wayfor building large complex distributed aPplication.This paper study how to combine CORBA with Web, how to build anapplication system of many tiers. CORBA and Web technology both haveadvantage and shortcoming, and they can remedy each other. It is focus tobuild many tiers and large application by the combination of CORBA andWeb.The seven chaPters included this paPer is as follows:The first chapter briefly introduces the history of Web technology'CORBA and Object Web, explains the study signification.The second chapter details the history of distributed computing,analysises collected computing model and distributed computing model and atlast introduces middleware and distributed object technology.The third chapter brings forward the three kinds of technology whichsupport distributed object.The forth chapter discusses how to build the Object Web with VisiBrokerfor Java.Chapter five introduces the system design.Chapter six includes software implement and some key technology during programming.The seventh chapter gives the paper conclusion.Project is supported by Nature Science Foundation of Hubei province.
