应用系统中的资源及资源管理

应用系统泛指各种计算机信息系统，它以提高资源的共享与利用率为目标。目前，应用系统中的资源通常指数据资源，对系统的管理和维护仅有数据资源远远不够，还应包括程序资源和网络资源。有效而合理地管理好这些资源是确保应用系统处于良好运行状态的关键。通过对应用系统中各种资源的分析，提出了资源管理的基本模式与策略，讨论了基于资源为中心的应用系统构架，探讨了建立资源管理系统的思路。资源管理系统将应用系统与系统中的资源有机地联系起来，为系统的应用和进一步开发奠定了较好基础。

Resource Management in Application System

Application system generally refers to all kinds of computer information system. It aims at improving the sharing and application of the resource. The resource in application system usually means data resource. For computer management and maintenance, there are not only data resource, but also program resource and network resource. Effective management of this resource is key to ensure proper work of the application system. In this paper, the basic pattern and policy for resource management is put forward and a method to build and realize the resource layer that lies between database layer and application layer is to be found. This management layer, which skillfully connects the application system with resource and establishes good base for application and exploitation of system, is named as resource management system.
