| Research Abstract |
XML (Extensible Markup Language) has widely been used as a standardized data format in wide spectrum of applications, and XML stream, where data records represented usingXML are continuously transmitted as data streams, has been gaining its popularity due to the mergence and proliferation of sensor networks and M2M (Machine-to-Machine) applications. Meanwhile, the demand to perform analytical processing over XML streams rather than simple query retrieval is increasing. To this problem, in this research, we have studied the schemes for online analytical processing over XML streams.
