This paper presents a method of converting relational database into XML documents,that is de-normalization and *** the principle and implementation of the method are *** method involves three steps. Firstly,we revert the normal relation schema to original unnormal one without the functional dependency,transfer functional dependency,multivalued dependency and join *** urmormal relation tables are called connection *** the connection tables are changed to XML documents and XML *** the end,all those XML documents are *** to the principle, the method is implemented in the case of bank *** this example,the data demonstrate the validity and feasibility of the method.
