基于虚拟视图的网络化数据共享

Data Sharing Based on Virtual View in Network

提出了一种基于虚拟视图的网络化数据共享方法。该方法在网络化环境中,具有开放性和灵活性,支持跨多个数据源进行数据共享,可将数据源按照规范进行注册,并建立可以跨多个数据源的虚拟视图,由数据共享查询服务进行虚拟视图的查询请求解析、查询分解、数据获取和结果合成,以获得最终所需数据。

A data sharing platform in network environment is proposed based on the virtual view. The platform is open and agile, thus it can be used in data sharing across different data sources. On the platform data sources are registered according to the specifications, and virtual views are created across different data sources. The query service is responsible for parsing of the virtual view request, querying decomposition, data acquisition, and result synthesis to generate the final data.
