| Abstract: | At present,the problems of too many data tables generated and too low efficiency in querying are general in the method of mapping XML document to relational database.For this reason,a mapping method with Dewey encoding based on model mapping is proposed,which gives the logical structure model of the mapping,detailed design,the mapping algorithm and experimental results.The experimental results show that the structure of data tables generated by this method is simple.Compared with the traditional algorithm,this method has some performance advantages in document resolving and data querying. |
