Using XML packets replacing the original fixed-length packets, the new system integrates all the process of each service running on the background core machine, this improves its efficiency and accuracy, to achieve more than one tally in a communication, and provides the critical data which the query module needs. Meanwhile, the U-Topk query and the probability database was introduced in the new system which help establishing a series of possible worlds, and has some improvements in possible worlds and algorithms of U-Topk.
