Abstract :
Schema integration is an important discipline for constructing a heterogeneous database system. The task becomes particularly challenging when involves the resolution of naming, structural and semantic conflicts. We present a method to integrating tables with structural conflict via the global metadata database (GMDB) and rule base. The method let user pose fuzzy query and comes back all possible results.
