Main memory database for supporting database migration

As one of the new technologies to make good use of broader channel bandwidth of recent networks, dynamic relocation of databases through networks, which we carl database migration, will soon become a powerful and basic database operation of practical use. To make full use of database migration, the main memory database is considered to be one of the most significant technologies, because it allows us to perform very high speed database access which almost matches for the transmission rate of broadband networks. In tills paper, we first discuss the physical database structure which realizes high speed database migration. Then, we propose the recovery methods for migratory main memory databases.
