Incremental Data Migration for Multi-Database Systems

Access this Article

Abstract

Nowadays, database systems are one of the most popular and essential software programs in computer systems. Many computers are installed a database system and users maybe want to use these database systems as one system. The multi-database system is one of the solutions to this request. The multi-database system is a kind of the distributed database system. It is a cluster of independent database systems. As the distributed database system, the multi-database system has some problems. One of these problems is data migration among individual database systems in the multi-database system. Many reorganization techniques for distributed database systems already proposed. But these techniques are not always adaptive to the data migration in the multidatabase system. In order to overcome this problem, we adapt the incremental scheme to the data migration in the multidatabase system. In our new scheme, a large data migration operation is divided into small ones, and other operations are inserted between them. The experimental result proves the improvement of the turn-around times of other operations.
