Abstract :
We propose a novel directory scheme for a large federation of databases where object migration is in response to manufacturing events. In our directory scheme, objects report their location to a directory server instead of the traditional method of the directory servers polling sites in the network. The directory is distributed among multiple servers to avoid bottlenecks during query processing. A distributed linear hashing algorithm is proposed for efficiently determining an appropriate server for an object. Finally, a stochastic dynamic programming model is proposed for minimizing the number of database transactions
