数据库系统是当今计算机系统中最流行、最基本的软件程序之一。许多计算机都安装了一个数据库系统，用户可能希望将这些数据库系统作为一个系统使用。多数据库系统就是解决这一要求的方案之一。多数据库系统是一种分布式数据库系统。它是一群独立的数据库系统。作为分布式数据库系统，多数据库系统存在一些问题。这些问题之一是多数据库系统中各个数据库系统之间的数据迁移。已经提出了许多分布式数据库系统的重组技术。但这些技术并不总是适用于多数据库系统中的数据迁移。为了克服这一问题，我们将增量方案应用于多数据库系统中的数据迁移。在我们的新方案中，将大数据迁移操作划分为小操作，并在它们之间插入其他操作。实验结果证明，改进了其他操作的周转时间。
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.
