Query optimization is a key point of distributed database (DDB) system, while optimization of join queries is especially important considering it's been widely used. In this paper, we discuss common optimization method of join queries within DDB system, and then give an intensive description of join optimization based on pre-test technology we applied, we make final analyses and conclusions of this paper at last.
