The characteristic of data stream is that it has a huge size and its data change continually, which need to be responded quickly, since the times of query is limited. The continuous query and data stream approximate query model are introduced in this paper. Then, the query optimization of data stream and traditional database are compared. Finally, Technology of continuous query optimization over data streams was investigated.
