XML Data Allocation in Hard Disks Based on Query Patterns
Xuehua Jiang, Haruo Yokota · 2011
Applications of XML data are becoming more and more active and their volume is increasing day by day. To save high capacity of XML data, more than one hard disks are used. Decreasing power cost consumed by multiple hard disks and increasing XML data retrieving performance are important problems. This paper proposes an allocation algorithm for XML data in multiple hard disks by finding out XML tree/subtrees which are often issued together during the same transaction and put them into the same disk in order to reduce power consumption and enhance retrieve performance.
