| Abstract: | In this paper, from databases design,we study further on XML database constraint. XML functional dependency is presented based on path expression and tree model. From the implementing of data exchang between heterogeneous databases with XML, it has important theoretic significance and practical value to the research on XML database schema normalization. |
