通过以关系名的同义关键字作为模式信息的索引键以及垂直分区关系元组,设计了用结构化重叠网络索引模式和数据的方法。基于这两级索引,提出了支持多属性复杂查询的算法。定性分析和比较表明,该方法比相关工作更接近P2P数据管理的理想目标。
By using relation keywords as indexing key for schema info and partitioning tuples vertically, a method of indexing both schema and data with structured overlay was designed. Then, an algorithm based on these two levels of indices to support complex queries on multiple attributes was proposed. Qualitative analysis and comparison show that this work is closer to the goal of P2P data management than other projects.
