Zhang Lai-shun · Jisuanji gongcheng yu sheji · 2008
Exclusive operations are an important control mechanism to ensure data consistency.Based on the analysis of existing XML access control model, the possible inconsistencies is proposed, which is brought by different types of operation in model definition.The cases of this inconsistency in all the circumstances are formally described, then a series ofthe primitive language is proposed with locking control mechanism to resolve the issue.Final adoption ofspecific algorithms achieve multiple users simultaneously request exclusive operating methods.
