Solving Data Exchange Problem Based On Improved Chase Approach
Data exchange is one of the key problems of information integration. The most important process in data exchange problem is how to solute it based on circulatory dependence. In this paper, we proposed an improved chase approach in the special background of application for the data exchange. Solving the problem that finding the most approximately solution in polynomial time for data exchange problem by amending the dependence condition appropriately.
