摘要
异构数据的查询是近年来研究的热点,用户不能同时对异构数据进行查询。提出一种基于JSON的异构数据查询方法,该方法以JSON传输格式为基础,为不同设备端提供访问异构数据源的接口,使JSON作为统一的模型对异构数据进行编写。使用JSON格式的数据查询方法可以为用户节省流量成本,同时简化了对异构数据的查询问题。理论分析和实验结果证明基于JSON的异构数据查询算法具有高效、稳定的优势。
The heterogeneous data query has been a hot spot in the current study. Since users cannot query the heterogeneous data synchronizedly, this paper presents a query method of heterogeneous data based on JSON. The method takes JSON as a foundation of transmission format for different equipment, and provides interface to access heterogeneous data. This makes JSON as a unified compiling model of data. Meanwhile, the method can save the flow cost, and simplify the heterogeneous data query problem. Theoretical analysis and experimental results show that the query method of heterogeneous data based on JSON has advantages in terms of efficiency and stability.
