  7. 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
