摘要 研究了如何利用查询和视图来解决半结构化数据查询重写问题.给出了一种OEM数据模型和一种半结构化数据查询重写算法.算法借用了半结构化数据查询重写桶算法的思想,解决了半结构化数据模型之下查询重写的一些新问题.理论分析表明,它降低了算法的代价. How to use querying and views to solve semi-structuretured data query rewriting is researched. A semi-structuretured data model and a kind of semi-structuretured data query rewriting algorithm are given. Some new problems for semi-structuretured data query rewriting are solved based on semi-structuretured data query rewriting bucket algorithm. Theoretical analysis proves that the approach reduces the cost of algorithm.
