The Research on Data Resources Sharing of Water Resources Domain Based on Proactive Service

摘要

It is a key issue to the distributed and heterogeneous domain data resource sharing. In this paper a new mode of water resources data sharing is proposed from the point of proactive service. At first, a data sharing framework, called FDSWRDPS, is provided based on SOA and domain ontology. Then service factory is used for a design pattern of data integration subsystem. Furthermore proactive service is implemented based on event-trigger mechanism. Integrated domain data can be pushed to users automatically by using FDSWRDPS.
