Research on Fixing Inconsistencies in Spatiotemporal XML Document
Zongmin Ma · Journal of Northeastern University · 2012
As being the core and the base of spatiotemporal database,a considerable amount of spatiotemporal data models have been proposed to enable the increasing applications.However,less research has been done in modeling spatiotemporal data based on XML,especially in fixing inconsistencies of spatiotemporal data in XML document.A spatiotemporal data model based on XML was established.On the basis of the model,consistency conditions of spatiotemporal data in XML document were given.In succession,how to fix inconsistencies of the three primitive change operations,namely update,insert,and delete,were demonstrated. Subsequently,examples were given to illustrate approaches for fixing inconsistencies.Finally,types of inconsistencies of the three primitive change operations were discussed.
