The Exchange and Integration of Heterogeneous Data with Uncertainty for Emergency System
Liu Yucheng, Yang Xiao-yi, Jun Chen · 2008
Aimed at the puzzle to realize exchange and integration for heterogeneous data, this paper proposed a sort of data exchange model of heterogeneous database based on middleware unified platform. Based on the mapping of model drive, the data exchange could be realized by a concrete model. Its thought was to express XML document being a tree composed by data object, in which each element type corresponded to an object in object pattern, namely there was mapping among patterns. The paper gave an example of power emergency processing system, the application effect shows that the speed of emergency event processing can enhance five to ten times and it is able to realize the exchange and integration for heterogeneous data easily.
