XML Concurrency Control Protocol Based on Local Path Locking
Ying Guan · Jisuanji gongcheng · 2010
Traditional XML database concurrency control protocols are almost based on the path locking model of XML document tree and it can not provide high concurrency.Aiming at this problem,this paper proposes an XML database concurrency control based on local path locking model.This protocol goes on node coding based XML,uses the scan function to judge the locking status of the target node ancestor and descendant,locks the target node or its parent node according to the operation type to reduce the frequent request for lock,improves concurrency for transaction and realizes the efficient management for large-scale XML data.
