  • Semantic analyse of data request , query decomposition and conversion rules are introduced in detail
    詳細(xì)介紹了數(shù)據(jù)交換引擎中數(shù)據(jù)請求的語義分析、查詢分解、構(gòu)建轉(zhuǎn)換規(guī)則等功能模塊的作用及工作原理。
  • Sometimes the huge relevant information in those databases should be managed unitedly , , so , it is getting more and more critical to develop applications for building systems that combine relevant data from database sources and present them in a form which is comprehensible for users beginning with the basic theory of module and distributed multidatabase , this paper discusses the technologies about the ejb , corba component used in the oracle8i / 9i database , the schema integration and query decomposition , , schema integration and query decomposition are key segment of this thesis
    某些情況下，這些數(shù)據(jù)庫中的相關(guān)信息需要統(tǒng)一的進(jìn)行管理，這就迫切需要開發(fā)出相應(yīng)的應(yīng)用系統(tǒng)來集成多數(shù)據(jù)庫中的相關(guān)數(shù)據(jù)并使用戶能夠充分的理解。本文首先從組件和分布式多數(shù)據(jù)庫的基本原理出發(fā)，詳細(xì)討論了模式集成和查詢分解技術(shù)與ejb 、 corba等組件技術(shù)在oracle8i 9i數(shù)據(jù)庫中的應(yīng)用。數(shù)據(jù)模式集成和查詢分解是本文探討的重點，也是分布式多數(shù)據(jù)庫的核心內(nèi)容。
  • They are kernel knowledge of distributed multidatabase too0 then , based on a reasonable classified frame of schema collision , the paper probes into the strategies realizing schema integration and query decomposition using the good " low coupling , high cohesion " characteristics of component ; and then , a improved model of federal database architecture is designed exerting the virtue of independence and assembly of component < , at last , i had completed the work of developing a demo for the integration of audit information systems with the helps of others , which proved that the improved model of federal database architecture is practicalo
    我在提出一個合理的模式?jīng)_突分類框架的基礎(chǔ)上，探討了如何運用組件技術(shù)的低耦合、高內(nèi)聚的良好特性來實現(xiàn)數(shù)據(jù)模式集成和查詢分解的策略；同時，運用組件技術(shù)的獨立性和可裝配的優(yōu)點，設(shè)計了一個改進(jìn)的聯(lián)邦數(shù)據(jù)庫體系結(jié)構(gòu)模型。最后，在上述理論的指導(dǎo)下，本人與協(xié)作者完成了湖南省審計廳信息集成原型系統(tǒng)的設(shè)計和開發(fā)，總體上證實了改進(jìn)后聯(lián)邦數(shù)據(jù)庫體系結(jié)構(gòu)模型的可行性。
  • In this thesis , schema integration global query decomposition and optimization and global transactions manipulation in multidatabase systems are discoursed elaboratly . the algorithm which clears up one - to - one entity conflict and query process optimization algorithm are presented and analysiz . ed . the assurance strategy of transaction atomity and global deadlock resolution algorithm are also discussed in this thesis . at end of this thesis , based on domestic experiences and overseas experiences , a new multidatabase system model is presented by combining multidatabase system and corba technology , and security management mechanism is introduced in this model
    本文對多數(shù)據(jù)庫系統(tǒng)中模式集成、全局查詢的分解和優(yōu)化以及全局事務(wù)的處理等問題進(jìn)行了詳細(xì)而深入的論述，給出了一對一實體沖突的消解算法和查詢處理優(yōu)化算法，并對這些算法進(jìn)行了分析；同時還論述了事務(wù)原子性的保證策略和全局死鎖的處理算法。最后，本文在借鑒國內(nèi)外經(jīng)驗的基礎(chǔ)上，把通用對象請求代理結(jié)構(gòu)技術(shù)與多數(shù)據(jù)庫系統(tǒng)結(jié)合起來，提出了一個新的多數(shù)據(jù)庫系統(tǒng)模型，在該模型中引入了安全管理機(jī)制。
  • Chapter 3 presents a method to represent schema architecture and schema mapping , prescribe an algorithm for decomposition tree . chapter 4 describes the implementation framework of multidatabase query processing , the implementation algorithm of query decomposition , approaches of query in the cmdatabase will be addressed
    第三章提出了多數(shù)據(jù)庫系統(tǒng)cmdatabase的模式結(jié)構(gòu)及模式映射方法，定義了用于多數(shù)據(jù)庫查詢處理的樹生成算法第四章描述了cmdatabase的全局查詢處理的查詢分解算法。
