  1. 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。
  2. 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。
  3.
