The Study on a Method of De-Normalization and Synthesis

摘要：

This paper presents a method of converting relational database into XML documents,that is de-normalization and synthesis.Both the principle and implementation of the method are discussed.This 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 dependency.These unnormal relation tables are called connection tables.Then the connection tables are changed to XML documents and XML tree.In the end,all those XML documents are merged.According to the principle,the method is implemented in the case of bank loan.In this example,the data demonstrate the validity and feasibility of the method.
