为促进网格环境下数据资源的共享,增强网格应用对现有数据访问的支持,针对资源的异构集成与透明访问问题,利用LDAP协议和LINQ技术提出一种基于网格的多源数据访问模型,并论述模型结构和关键模块的实现原理.该模型可实现对数据库、XML文档、ADO.NET数据集、内存数组集合等数据源的透明访问.
為促進網格環境下數據資源的共享,增彊網格應用對現有數據訪問的支持,針對資源的異構集成與透明訪問問題,利用LDAP協議和LINQ技術提齣一種基于網格的多源數據訪問模型,併論述模型結構和關鍵模塊的實現原理.該模型可實現對數據庫、XML文檔、ADO.NET數據集、內存數組集閤等數據源的透明訪問.

Aiming at the theme of accessing heterogeneous data transparently, a model for the access to data resources in the grid is put forward in this paper, taking advantage of Lightweight Directory Access Protocol(LDAP) and Language Integrated Query(LINQ) to enhance the resource sharing and advance the support of the access to existing data for applications in the background of the grid. The structure and key technologies are emphasized. This model realizes the access to multi-resource, such as SQL database, XML document, ADO.NET dataset, list in memory.
