摘要 在信息网格资源的层次模型[2]中,虚拟视图层直接反映行业用户的资源访问需求。虚拟视图层到逻辑资源层映射的正确性,是使用虚拟视图进行信息网格资源访问的基础。业务逻辑的变化可能引起逻辑资源层元数据的变化,导致虚拟视图到逻辑资源的映射失效,用户使用虚拟视图无法得到预期的结果。该文讨论了逻辑资源层元数据发生变化的各种情况,并提出了相应的虚拟视图调整方法,以维护虚拟视图层元数据的有效性。 In the layered resource space model of information grid, the virtual view layer directly reflects industrial users' request of resource access. To access resources using virtual views, users must guarantee the validity of mappings between the metadata of virtual view layer and logical resource layer. Unfortunately, evolution of the metadata of logical resource layer may invalidate such mappings, and users can not get expected results by using virtual views. This paper discusses different types of the resource layer changes. Then it proposes adapting algorithms to preserve the affected virtual views.
