A study of optimized algorithm for distributed data query
Xiuxia Yu · Journal of Changchun University · 2006
The distributed data query is the core of the distributed database managing system,but the optimized query algorithm is the key technology in query processing.Because of the decentralization of the distributed data,making the distributed data query is more complex than the concentration data.The optimized algorithm based on relation algebra is studied and discussed in this paper,it has been applied in example,obtained better the optimized result.
