摘要: 搜集近几年提出的各种XML压缩方法,比较、分析具有代表性的XML压缩技术。实验表明,XMill拥有出色的压缩率、较少的压缩与解压时间、较低的内存消耗,以及最优的平均压缩性能,但不支持对压缩文档的直接查询。XGRIND与XPRESS的压缩性能不如XMill,却能较好地支持对压缩文档的直接查询。总结XML压缩方法各自的优点和不足,并探讨未来努力的方向。

关键词: XML压缩, Web应用, 查询处理

Abstract: This paper collects multifarious XML-conscious compression methods which are proposed recently, compares and analyzes the state-of-the-art XML-conscious compression technologies. The result of experiment shows that XMill has the best compression ratio, less compression and decompression times, lower memory consume, and obtains the best even compression performance. But it does not support to query compressed document directly. On the other hand, the compression performance of XGRIND and PRESS are far worse than XMill, but they support to query compressed document directly. It points out their merits and deficiency, and discusses further works.

Key words: XML compression, Web application, query processing
