    動作a包括兩種情況:第一,物化視圖的語義和數據量增加了第二,物化視圖的語義和數據量減少了。
  2. If relevant, then checks whether it is concurrent incremental maintainable or self - maintainable. if the update satisfies self - maintenance, our mechanism queries auxiliary views ( instead of querying iss ) to avoid network transmission and make the materialized view consistent with underlying iss. the update which needs to maintain the view concurrently and incrementally can be handled by polec

    當收到更新后, pmdvm方法首先用相關性對其檢查,對不相關更新直接拋棄;對相關更新對其進行並發增量視圖維護或自維護機制檢查,對滿足自維護的更新通過查詢輔助視圖(而不是查詢數據源)來避兔網路傳輸和使實化視圖與底層的數據源保持一致,對必須進行並發增量視圖維護的更新由polec來處理。
  3. We mainly present view selection algorithm based on mining frequent query patterns, cache loading algorithm, view - based xml query processing algorithm and incremental xml maintenance algorithm for various update operations

    我們主要給出了基於頻繁查詢模式的視圖選擇演算法、緩存裝入演算法、查詢可回答性定義、基於視圖的查詢處理演算法以及針對多種更新的視圖維護演算法。
  4. The paper , via building performance model of boiler - turbine unit , to online determinate curve of consumption in power plant which provides reliable thereunder for realizing load optimal distribution , in view of optimal distribution arithmetic , the improved equal incremental principle and linear programming are adopted , meanwhile , the database with online data disposal and data management is realized

    通過建立各單元機組的性能模型,在線確定機組的耗量特性曲線,為實現負荷最優分配提供了可靠的依據;在負荷分配演算法上採用了等微增率原理和動態規劃方法,並對現有演算法進行了改進;同時開發了具有在線數據處理能力和歷史數據管理能力的數據庫。
  5. Currently, only few works has addressed it. crucial problems still required in - depth research, such as view selection for caching, view based xml query processing and incremental maintenance of xml views

    目前,關于這方面的研究方興未艾,如何選擇合適的xml實體化視圖進行緩存,如何利用緩存的視圖結果處理xml查詢以及如何增量維護xml視圖等等都是十分值得研究的問題。
  6. We believe that such a view does not match the reality of incremental adoption that is likely to occur, nor the diversity of pervasive - computing device vendors that will doubtless proliferate

    我們認為這種觀點既與可能越來越多的採用這種方案這個現實矛盾,又與各普及運算設備供應商無疑會擴大生產的多樣性相矛盾。
  7. We show that the warehouse views can be made self - maintainable with the auxiliary views, which derived from the intermediate result of the view computation can be materialized in the warehouse. the incremental maintenance algorithm can implement warehouse real - time updating

    文中介紹了一種利用視圖計算的中間結果創建輔助視圖,在數據倉庫中進行實體化,計算實視圖和輔助視圖的精確變化,實現數據倉庫的增量維護演算法。
  8. After receiving the updates from iss, the materialized views are re - evaluated incrementally by use of the algorithm such as ega, strobe and olec etc. olec algorithm overcomes the disadvantages of ega and strobe without additional local compensation and dw no need to be static when incremental view commits

    Olec演算法克服了eca演算法和strobe演算法的缺點,它不需要額外的本地補償操作,視圖增量提交時也不需要數據倉處于靜止狀態。
  9. To support cache item view, the policy uses incremental view maintenance. because of the high cost of maintaining cache coherency and the resource - poor characteristic of mobile environments, the thesis also discusses cache weak coherency. several ways to specify allowable divergence are given
