  3. This paper stresses on discussing the architecture, access protocol and implementation mechanism based on xml and web services technologies, researches key technologies of metadata information service and data uniform access and management in database grid, designs and implements distributed mis subsystem and das subsystem, which support multi - domain management. mis can provides metadata information for the whole system, such as das and clients, it uses domain name 、 logical name and internal name of data object to uniformly name database resources in grid and implements name mapping mechanism and user view metadata information service and provides virtual organization and management of database resources. das can provide a scalable uniform data access by virtual organization and management of storage resources and multi - mode data share access mechanism, thus integrate database resources in grid and shields distribution and heterogeneity of resources and achieves transparent access. system adopts data access mechanism based on user request mapping to flexibly implement data access across multi domains, and adopts distributed data cache mechanism 、 security mechanism based gsi to provide high - performance secure data service for grid users

    本文論述了griddaen - dai系統的邏輯結構、訪問協議、數據服務流程以及基於webservices 、 xml等技術的實現策略，重點研究數據庫網格中的元服務、數據統一訪問和管理等關鍵技術，設計和實現了支持多管理域的分散式元服務子系統和數據訪問服務子系統。其中元服務主要為整個系統提供各種元信息支持，它採用域名、數據對象的邏輯名稱、物理名稱和內部名稱對廣域環境下的數據庫數據進行了統一命名，實現了相應的名字映射機制和全局的用戶數據視圖服務，提供了數據庫資源的虛擬組織與管理方式;數據訪問服務通過提供可擴展的統一數據訪問和支持多種數據共享訪問模式，屏蔽了數據庫資源的分佈性和異構性，為用戶提供了統一透明的數據服務。
  4. In this thesis, the database of gps vehicle monitor information management system is designed, the design of the man - machine conversation interface and the software of the database server, also the software of the mid - ware are accomplished. an improved and logical three layer structure framework is used to utilize the resource of the system efficiently, balance the load, and improve the expansibility of the system ; powerful oracle database is used as background database to provide high performance service to the system which has numerous users and large - scale ; encrpytion arithmetic of communication data is designed to ensure the safty of gps vehicle monitor information management system communication ; the usage of fire wall, system privilege management and data backup improved the safty of the information management system database ; high usability design is realized by oracle data guard ; optimization of the information management system made the whole gps vehicle monitor system persistent, stable and high quality

    本文針對原有gps車輛監控系統響應速度慢、穩定性和安全性不高的不足，提出了一種以改進的三層結構體系為系統架構，以oracle數據庫為后臺的gps車輛監控信息管理系統設計方案，設計了gps車輛監控信息管理系統數據庫，完成了gps車輛監控信息管理系統人機界面、中間件及數據庫端的軟體設計。系統架構採用改進的三層結構體系，其邏輯結構清晰，有利於系統資源的有效利用，均衡負載，提高系統的可擴展性;后臺數據庫採用功能強大的oracle數據庫，可以提供大規模、多用戶的高性能服務;通信數據的加密演算法有利於確保gps車輛監控信息管理系統的通信安全;防火墻的使用、系統權限管理以及數據的備份和恢復等有利於提高gps車輛監控信息管理系統數據庫的安全性， oracledataguard的使用有利於提高系統的可用性;系統的優化，為系統持續、穩定、高質量運行創造了有利條件。
