Native Temporal Slicing Support for XML Databases

XML databases, providing structural query-ing support, are becoming more and more popular. As weknow, XML data may change over time and providing ane±cient support to queries which also involve temporalaspects is still an open issue. In this paper we presentour native Temporal XML Query Processor, which ex-ploits an ad-hoc temporal indexing scheme relying on re-lational approaches and a technology supporting temporalslicing. As we show through an extensive experimentalevaluation, our solution achieves good e±ciency results,outperforming stratum-based solutions when dealing withtime-related application requirements while continuing toguarantee good performance in traditional scenarios

As we know, XML data may change over time and providing an efficient support to queries which also involve temporal aspects is still an open issue. In this paper we present our native Temporal XML Query Processor, which exploits an ad-hoc temporal indexing scheme relying on relational approaches and a technology supporting temporal slicing.
