Data resource management according to customer requirements

Data resources have the characteristics of heterogeneity and differentiation; with increasing demand and the development of the scale of application systems, data resources must be constantly enriched and expanded. The traditional data resource management model has been unable tomeet users’ requirements of flexibility, timeliness and expansion in data resource management, which has led to major bottlenecks in system applications, cost increase and lower efficiency. We propose a method of data resource management using on-demand customizing that can be used to solve the problems stated above: on the basis of analysis of the data resources, the flexible management and customization of data resources is realized, eliminating the tight coupling between information system data storage programs and data resources, and providing transparent, flexible data resource management for enterprise applications, thus ensuring the sustainable development of information systems. © 2010 Elsevier Ltd.
