In broadband networks, appropriate use of database migration can drastically shorten the average transaction processing time of a distributed database system. In previous work, we have proposed a transaction processing method based on database migration, in which we assumed that the network bandwidth is very broad and almost uniform over the whole network. However, WANs consist of various types of networks, including private LANs, narrowband public networks and broadband backbones; thus, that method cannot be applied migration scheduling method which gives that shortest communication time for database operations, and is suitable for use in WANs. We also prove that the proposed method can find the database migration schedule which gives the shortest communication time for a given access sequence.
