  1. Aiming at this problem, the main research issues and achievements in this paper are as follows : bi - directional data transformation between rdb and xml with semantic constraints preserved for most of existing researches on static data transformation between xml and rdb, dtd is taken as the schema description language for xml, and the semantic constraints are often lost during the transformation process. to overcome these disadvantages, the author adopts xml - schema, a standard schema description language proposed by w3c to replace dtd, as the description method owing to its more powerful functions than dtd, and of course with the syntax much more complicated. after analyzing the constraints characteristics in both xml - schema and relational schema, a semantic constraints - preserved algorithm is proposed which can realize the bi - directional schema mapping between rdb and xml through a formalized description of xml based on regular tree and a general expression for relational schema based on direct graph approach

    保留語義約束的xml與rdb雙向靜態數據轉換技術現有研究大多採用dtd ( documenttypedefinition ,文檔類型定義)作為xml的模式描述語言,並且在模式映射過程中丟失語義約束信息,本文分析了xml - schema ( xml - schema採用與dtd完全不同的語法,數據描述能力更強同時也更為復雜,已被w3c確定為替代dtd作為xml模式描述語言的標準)及關系模式的語義約束特徵,通過基於正則樹的xml形式化描述方法以及基於有向圖的一般關系模式表示方法的研究,建立保留語義約束的xml - schema與關系模式的雙向模式映射演算法,實現了xml與rdb的雙向數據轉換,較好地解決了xml與rdb在靜態數據轉換層面的數據集成問題,可有效滿足企業大量rdb數據面向xml的發布以及與日俱增的xml數據存入rdb的應用需求。
  2. Designing and calculating subsystem is the core of the whole system. it is based on the limit design method of bearing, designs parameter depend on relational data base and transmit the datum that has been searched to graph managing subsystem through data interface

    設計計運算元系統是本系統的核心,它以「軸承極限負荷設計法」作為設計基礎,應用關系型數據庫管理設計參數,並通過數據介面將檢索出的數據傳遞給圖形處理子系統。
  3. In autoore, a novel approach to extract java semantic relational model is presented. to get precise object relational result, the java code polymorphism invoke location is formal defined and a program analysis method based on extended class hierarchy graph ( echg ) is proposed

    代碼抽取是oore的起點,從起點開始支持理解是逆向工程的重要目標, autoore在java抽取中,抽取模型採用文中提出的java詞法和語義兩個模型,利用一個基於java擴展類層次圖( echg )的多態調用點分析演算法,得到更精確的靜態對象關系。
  4. The organization of data : first, the author introduced the data structure of maplnfo and studied file structures of the data and the mechanism of connection ( especially the connection of graph & data ). then, the author works out the model of the data ' s structure of this system and set up database of classifying land that based on the model of relational database

    數據組織:首先簡要介紹了mapinfo的數據組織結構,研究了構成mapinfo的數據文件結構及連接機制(特別是圖?數連接機制) ;然後在此基礎上設計出系統的數據組織模式,建立了基於關系數據庫模型的土地分類數據庫。
  5. 3 ) presentation and implementation of key - based relational schema reverse reconstruction algorithm ( krr ). based on discrete mathematics theory, a krr algorithm is proposed which can realize the transformation from relational schema to directed graph structure and get a good data preparation for the sequential schema mapping

    3 )提出基於key的關系模式重構演算法以離散數學理論為基礎,對關系模式數學建模,通過提出基於key的關系模式重構演算法,將關系模式轉化為有向圖數據結構,為模式映射提供基礎。
