  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。
