Transformation of fuzzy spatiotemporal data from XML to object-oriented database

The rapid development of the Internet promotes that XML is increasingly accepted as a medium for integrating and exchanging data. Meanwhile, object-oriented database with many excellent properties has been applied more and more widely. In particular, considering the need of processing the fuzzy spatiotemporal data existing in practical applications, we study the methodology of building fuzzy spatiotemporal data model and transforming fuzzy spatiotemporal data from XML to object-oriented database as well. To establish a suitable model, we devise a fuzzy spatiotemporal data model in XML to capture the semantics of fuzzy spatiotemporal features. In addition, we take the object-oriented schema that best describes the exciting fuzzy XML Schema and the characteristics of the XML tree structure into account to develop a series of rules to map spatiotemporal data from XML to object-oriented database. Such mapping rules could provide a significant consolidation of the interoperability of fuzzy spatiotemporal data from XML to object-oriented databases.
