In this paper, we developed a new dom api locking protocol (DLP) that adopts the dom structure for locking. In order to enhance the concurrency and system performance, we studied operation conflicts more detailedly. The proposed DLP supports more update operations than the others, and does not imply more locking costs. Finally, we conducted several experiments to compare with the others and to observe the DLP performance under different workload parameters.

How to retrieve and query large XML documents efficiently has become a challenge in the database field for several years. A few efforts have been made in the past to address this *** this paper, we present a novel approach using pagination technique and index structure in a native XML database system named CanStoreX. The system is able to handle very large XML documents efficiently using only a small amount of memory space. The experimental results have shown that the index structure proposed in this paper could dramatically improve the performance of the XQuery engine on a pagination based native XML storage.
