A survey of semantic enterprise information integration

Based on a discussion of data understanding hierarchy, this paper reviews a state of the art of existing enterprise information integration solutions from semantic perspective. We divide existing approaches into three categories: programming semantic-based integration, syntax schema-based integration, and declarative semantic-based Integration, and evaluate the approaches in each category by comparing the method used to describe and explain the data, and the topology structure of the data connected. Based on the results of our analysis we summarize the state-of-the-art in semantic enterprise information integration and give the tendencies of further research.
