LI Yuanyi · Jisuanji gongcheng · 2005
Now there are a few researches on XML schemas and DTDs normalization design. Existing researches are still in the beginning. W. Provost proposes the idea applying the theory of relational database to XML schemas normalization design. This idea is not put into practice. The paper presents hierarchical schemas for representing XML schemas and DTDs and the procedure of hierarchical schemas design for XML schemas and DTDs normalization design, and analyzes produced hierarchical schemas. The set of full and embedded MVDs in hierarchical schemas produced by the algorithms are implied by the given set of MVDs.
