  2. 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

Then we use shuowenjiezi as well as the three standard books of chinese characters in tang dynasty, ganluzishu, wujingwenzi, jiujingziyang, as the criterion to correct the wrongly written characters, and divide the compiled common chinese words into seven categories : simplify the font, complicate the font, change the strokes, change the goujian, alternate the yifu or yinfu, alter the structure and kuaihuacaoshu. on the basis of that, we illustrate with the quantified data connected with the specifically speaking method that in the seven categories only two categories which are alter the yifu or yinfu and alter the structure maintain the reason of the standard form of chinese characters, the category of complicate the font weaken the reason, and the other four categories destroy the reason. through this, we can see that the reason of the common chinese words is much weaker than that of the standard form of chinese characters, so the common words are mostly excluded by the standard form system and are gradually obsoleted
