A main issue in database area is to process queries efficiently so that the user does not have to wait a long time to get an answer. However, there are many cases where it is not easy to accomplish this requirement. In addition, a fast answer could be more important for the user than receiving an accurate one. In other words, the precision of the query could be lessened, and an approximate answer could be returned, provided that it is much faster than the exact query processing and it has an acceptable accuracy.
