In view of the current database query process

in handling mass data

using conventional inquires the method not only waste the database resource

repeating the useless operations may make database burden and collapse

make inquires very time-consuming.This paper proposed to simulate an XML document database structure

database inquiry into an XML query.Using on proposed a more convenient inquires the solution.Computer simulation results proved that the query model can be vastly improved data query speed

and get a good effect.
