文献题目:The BIRD Numbering Scheme for XML and Tree Databases – Deciding and Reconstructing Tree Relations using Efficient Arithmetic Operations
摘要:
Abstract. This paper introduces the BIRD family of numbering schemes for tree databases, which is based on a structural summary such as the DataGuide. Given the BIRD IDs of two database nodes and the corresponding nodes in the structural summary we decide the extended XPath relations Child, Child+, Child\3, Following, NextSibling, NextSibling+, NextSibling\3
for the nodes without access to the database. Similarly we can reconstruct the parent node and neighbouring siblings of a given node. All decision and reconstruction steps are based on simple arithmetic operations. The BIRD scheme offers high expressivity and efficiency paired with modest storage demands. Compared to other identification schemes with similar expressivity,BIRD performs best in terms of both storage consumption and execution
time, with experiments underlining the crucial role of ID reconstruction in query evaluation. A very attractive feature of the BIRD scheme is that all extended XPath relations can be decided and reconstructed in constant time, i.e., independent of tree position and distance of the nodes involved. All results are shown to scale up to the multi-Gigabyte level.

文献题目:
XML的鸟编号模式和决定和重建树联系的树数据库–使用高效率的算术运算
摘要:
抽象的.本文介绍了鸟的家庭电话号码计划树数据库,这是基于一种结构性的总结,如dataguide .鉴于禽流IDS中的两个数据库节点和相应的节点,在结构上的总结,我们决定延长关系为节点,没有进入数据库.同样,我们可以重建母公司节点和邻近兄弟姐妹的一个特定节点.所有决定和重建步骤,是基于简单的算术运算.鸟计划提供了高表达和效率,搭配适度的存储需求.相对于其他鉴定计划,以类似表达,鸟表现最好的两方面而言,储存,消费和执行
当时,与实验强调关键作用的身份证重建质疑评价.是一个甚具吸引力的特点,鸟计划是,所有扩展XPath的关系可决定改在常数时间,即独立于树的位置和距离的节点.所有的搜索结果都显示,最高可扩充到多技嘉科技水平.
