忘掉螺栓、螺母、釘子，忘掉安裝吧。把你的工具留在你的箱子里。桌腿可以輕松地拆下，然後方便地打包運輸或儲存。 -
Firstly, it presents the storing arithmetic based on the mapping policy between xml data modal and object - oriented modal. reference to the arithmetic of extracting object - oriented database schemas from xml dtds using inheritance and other commercial tools for xml storing, it improves mapping policy from xml to object, which optimizes the new semantic classes, what ' s more, it present object clustering policy to resolve the uncertainty of xml schema and the complexity of information intergration, which simultaneously focuses on the semanteme and structure of new object classes. on the other hand, it presents method to realize exchanging from object to xml
本文研究構造基於xml信息集成系統結構的面向對象數據庫包裝器，提出面向對象數據庫包裝器的系統結構；根據該結構提出xml的數據模式與面向對象數據庫對象數據模式的映射策略及相互存儲轉化演算法，一方面我們借鑒基於dtd模式的繼承對象映射提取演算法及各種商業工具，提出dtd簡化演算法和基於dtd簡化結構的對象圖映射演算法，優化了生成的對象類、提高了對象類的語義表達能力，也改進了對象映射提取策略；同時採用模糊聚類策略，提出對象聚類處理演算法，改善了xml語義定義的隨意性給對象類提取及信息集成帶來的復雜性；另一方面本文提出對象到xml的轉化演算法，採用系統自動定義對象到xml的轉化方法實現對象到xml的轉化處理。 -
As the base of knowledge communication 、 communion and cooperation, ontology develops so far. however, there are still many problems going with its abroad applications : ontological engineering tools are short of currency, efficiency for ontology storing is low and it is difficult to express ontology query, and so on. in a word, it is short of effective system managing technology and method in ontology domain, exploitations of system for ontology management are imperative under the situation
本體論作為知識通信、共享、互操作的基礎而獲得了迅猛發展;但是在廣泛應用的過程中也暴露出了一些問題:本體構建工具缺乏通用性、本體存儲效率低下、本體查詢難以表達等等，即本體領域缺乏有效的系統管理技術與方法，本體管理系統的開發已經勢在必行。
