DataGuide-based Distribution for XML Documents.
Distribution is a well-known solution to increase performance and provide load balancing in case you need optimal resource utilization. Together with replication it also allows improved reliability, accessibility and fault-tolerance. However since the amount of data is large there is a problem of maintaining meta-information about distribution and finding needed data fragments during execution of queries. These problems are well understood but they have not received much attention in the context of XML data management. This paper presents research-in-progress, which examines the possibility of management of meta-information about XML data distribution extending auxillary index structure called DataGuide.Full text of the paper in pdf
