Abstract
Extensible markup language (XML) is increasingly accepted as a medium for integrating and exchanging data, gradually becoming de facto standard for information exchange. At the same time, object-oriented databases possess powerful data storage capabilities, especially with the widespread adoption of object-oriented database management systems. Consequently, the exchange of data from object-oriented databases to XML becomes crucial, and vice versa, transforming data from XML to object-oriented databases is equally important. In this chapter, the authors propose a comprehensive approach to achieve the transformation of spatiotemporal data between object-oriented databases and XML. We focus on exploring a set of mapping functions and rules to identify the most suitable XML schema that describes the existing object-oriented database. By leveraging the characteristics of XML and object-oriented databases, we successfully accomplish the transformation of spatiotemporal data. This research holds significant importance in achieving seamless data exchange between object-oriented databases and XML.
