| Abstract: | In this paper a novel data replication Architecture, called RAUT (Replication Architecture based on UD-Tree in distributed databases) is proposed. Different from existing work, this RAUT takes tree structure as major organization of the distributed databases. The main contributions are: (1) Two effective new algorithms based on the tree structure for data transportation between different sites are proposed. (2) The defects of the traditional model are overcome completely. (3) The traffic amount is reduced greatly, and the overall performance of the whole system is improved. (4) All algorithm are implemented and have been applied to the large distributed databases of CCIC(Chinese Crimes Information Centre) that consists of hundreds host computers from Ministry of Public Security, and the public security sectors of all levels widely spreading throughout China. |
