【正文】 r example, applied stress levels, number of functional pins, etc.) which is designed by system developers are important when puting failure rate of each ponent. It is important to obtain such data at a right moment for concurrent engineering. The client/server approach is perceived as an effective way to integrate puting resources in an organization. Users can share data, applications, and processing power in the client/server environment much easier than in the traditional centralized puting environment. The ability to balance the work load between clients and servers depending on the application is a key feature of the client/server system. The world wide web(WWW) has evolved into a vehicle supporting interactive data visualization and distribution. WWW greatly owns its success in the standardization aspect with the information being exchanged the clients and server. And also WWWbased systems can be built rapidly since no special resources are required when developing the client and server software or network protocols. In this paper, we describe the implementation of the reliability information system based on the technology of WWW and Client/Server. Section 2 provides a brief overview of WWW applied to the client/server puting. Section 3 introduces the implementation details of the reliability information system. And the conclusion and further study will be discussed in Section 4.2. WWW AND CLIENTSERVER ARCHITECTUREClient/server architecture can be explained as the relationship between two processes that are cooperating to perform some tasks. R supports the scalability and the integrity of an information system. Lyu (1995) discussed the four benefits of the client/server environment such as lower cost, higher productivity, longer system life cycle, and better usability. Therefore, the client/server system architecture is considered as a feasible framework for information systems. With the advent of the WWW, the most easiest way of implementing the client/server architecture is to use web browser where the client so ware does nothing more than display and format information retrieved from the server. Several kinds of retrieval system for bibliography are the representative examples. By using a web browser as the platform for client to access an existing client/server system, only one set of code(the HTML and helper code) for the system needs to be maintained. But in the case of other systems, where the client software performs additional tasks on behalf of the server or the users, the mediator is needed to perform this work for the web browserbased clients. The typical solution is to use mon gateway interface (CGI) programs. But this method is unsatisfactory for various reasons. With a CGIbased system, all work, normally done by th
