Dep artment of Comp uter , A nshan N ormal University , A nshan L iaoning 114005, China) Abstract: Data wa ehouse quality is ext ao dina y impo tant fo data wa ehouses. Data wa ehouse quality is the fitness fo use s. In this app oach, the autho eview lots of lite atu es on data wa e house quality and p esent a spatial data wa ehouse a chitectu e. It just base on it , the pape also p esent an efficiency methodology which can be used into building the quality metamodel. We can use it to evolve spatial data wa ehouses .
