| Abstract: | The query rewriting is a basic as well as a hot point in data integration system reserching.MiniCon algorithm is a kind of flexible and effective query rewrting algorithm.This paper tries to deeply introduce MiniCon algorithm and combine it with query capabilities of data sources.It solves the problem that not takes the query capabilities of actual data sources into consideration in MiniCon algorithm,and completes the query processing in LAV data intergration system. |
