  1. 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

    本文對多數據庫系統中模式集成、全局查詢的分解和優化以及全局事務的處理等問題進行了詳細而深入的論述,給出了一對一實體沖突的消解演算法和查詢處理優化演算法,並對這些演算法進行了分析;同時還論述了事務原子性的保證策略和全局死鎖的處理演算法。最後,本文在借鑒國內外經驗的基礎上,把通用對象請求代理結構技術與多數據庫系統結合起來,提出了一個新的多數據庫系統模型,在該模型中引入了安全管理機制。
