  1. 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。
  2. This thesis discusses the definition and implementation methods of hierarchical federations, and brings forward the technique of automatically constructing the hierarchical federations architecture ( hfa ). based on the study of time management and data distributed management in hierarchical federations, we give the constraint conditions, which need to be met for achieving correct temporal delivery of time - stamped messages and causal ordering of those messages. we propose the process of time advancement in hierarchical federations, and present the hierarchical data filtering mechanism, which can effectively decreases the network traffic

  3. It ' s an emergent requirement for the data communication bureau ( dcs ) of the china telecom company to develop a distributed business process schedule system ( dbpss ) for their business process management system named " data business computer integrated management system " - data 97. in this paper, by analyzing the business processes of the dcb, at first an integrated business process modeling method is put forward, then the architecture of dbpss are presented, and an integrated modeling and processes scheduler is designed and realized under the support of corba on starbus, which is developed by the institute of computer science in national university of defense technology. the solution proposed in this paper not only applies to " data 97 ", but also have much importance to develop other domains " scheduler

    本文以中國電信為應用背景，從「數據業務計算機綜合服務管理系統」 （簡稱「數據九七」 ）的實踐出發，以企業業務過程級集成為目標，通過對數據業務過程處理的分析，提出了企業業務過程建模和控制的方法，建立了分散式業務過程調度系統中各業務過程的抽象模型，並採用基於corba的分佈對象技術，設計完成了業務過程式控制制的總體結構和各功能結構之間的介面，進而實現了基於corba技術的分散式業務過程調度系統。
  4. We mainly discuss and make some contributions to the problems such as distributed architecture of wfms, xml process definition language, description and management of the workflow relevant data, encapsulation and transfer of parameters, agent for invoking extern application etc

    本文在分散式工作流系統體系結構、 xml過程定義語言、數據變量描述與處理、參數封裝與傳遞以及外部應用調用代理等方面做了一定的探討與創新。
  5. As the application of distributed computing is used much more widely ， distributed database becomes a significant part of information management it avoids a lot of disadvantages of conventional centralized database ， and is applicable to many situations distributed database is a set of data which is the unity logic ， but in fact these data is located on different sites it is of high availability ， easy expansibility ， high concurrency ， high efficiency and etc in distributed system ， data redundancy is a method to improve the speed of query and the availability of system distributed query should shield the lower level details of data redundancy from end users ， distributed transaction should ensure data from disaccord this paper introduces basic conceptions of distributed database firstly ， discusses distributed transaction and concurrent control ， describes the development prototype mysql ’ s characters ， architecture and executive mechanism ， then shows the skeleton model of dpsql and exposes the strategy and algorithm of distributed query and distributed transaction ， at last analyzes the extra expenses and response delay of distributed processes this paper exposes the implementation mechanism of distributed query and distributed transaction emphatically distributed query uses the strategy of “ read one ， write a11 ” s0 in such a system if user ’ s requests are read - - only for the most part and the distribution of data redundancy is plausible ， efficiency is very high distributed transaction uses two - 。 phase commit protocol to ensure the consistency of global data ， which has less communication overhead

    分散式查詢需要向用戶屏蔽數據冗餘分散的底層細節，分散式事務處理要保證全局數據完整，這都是傳統集中式數據庫不曾面臨的問題。本文首先介紹了分散式數據庫的概念性問題；接著討論了分散式事務涉及的定義及演算法；然後描述了dpsql的原型mysql的特性、結構和執行機制；繼而給出了dpsql的梗概模型，闡述了實現分散式查詢和分散式事務處理的策略及演算法；最後分析了進行分散式處理給系統增加的額外開銷和客戶端的額外響應延遲。本文重點描述了分散式查詢和分散式事務處理的實現機制，分散式查詢採用」讀一個寫全部」的本地優先策略，在讀操作頻繁的系統中，只要庫的分佈合理，單機效率極高，幾乎無任何附加開銷和延遲，而以整個系統的角度看來，吞吐量就更是優于單機系統；分散式事務處理採用兩階段提交協議，通信次數較少並能確實保證副本一致。
