我们考虑的问题,基于成本的策略,以获得有效的关系配置的XML应用程序,订阅一个XML模式。特别是,我们提出了一个灵活的框架,XML模式转换,并展示了它如何可以用来设计算法来搜索空间的等价关系配置。我们研究的模式转换和查询工作量的搜索策略,找到有效的XML到关系映射的影响。此外,我们提出了几个优化,以加快搜索过程。我们的实验表明,一个明智的选择的转换和搜索策略可以导致更高的质量比以前的方法推荐的关系配置。
We consider the problem of cost-based strategies to derive efficient relational configurations for XML applications that subscribe to an XML Schema. In particular, we propose a flexible framework for XML schema transformations and show how it can be used to design algorithms to search the space of equivalent relational configurations. We study the impact of the schema transformations and query workload on the search strategies for finding efficient XML-to-relational mappings. In addition, we propose several optimizations to speed up the search process. Our experiments indicate that a judicious choice of transformations and search strategies can lead to relational configurations of substantially higher quality than those recommended by previous approaches.
