- The information system of corporations are facing a new environment expressed by miniaturization. decentralization and Open System. It is therefore of utmost importance for corporations to adapt flexibly to such new environment by providing for corresponding changes to their existing information systems. The objectives of this study are to identify this new environment faced by todays information system and develop effective methods for data resource management under this new environment. In this study, it is assumed that the new environment faced by information systems can be specified as Distributed Computing Environment. and in order to achieve such system, presents Client/Server architecture as its representative computing structure. This study defines Client/Server architecture as a computing architecture which specialize the fuctionality of the client system and the server system in order to have an application distribute and perform cooperative processing at the best platform. Furthermore. from among the five structures utilized in client/server architecture for distribution and cooperative processing of application between server and client. this study presents two different data management methods under the client/server environment: one is "Remote Data Management Method" which uses file server or database server and the other is "Distributed Data Management Method" using distributed database management system. The result of this study leads to the conclusion that in the client/server environmemt. although distributed application is assumed. the data could become centralized (in the case of file server or database server) or decentralized (in the case of distributed database system) and the data management method through a distributed database system where complete responsibility and powers with respect to control of data used by the user are given not only is it more adaptable to modern flexible corporate environment. but in terms of system operation. it presents a more efficient data management alternative compared to existing data management methods in terms of cutting costs.
