  • 摘要:

    Due to the recent development of network technologies, broader channel bandwidth is becoming available everywhere in the world-wide networks. Based on this fact, we have proposed a new technology that makes good use of such broad bandwidth by dynamically relocating the databases through networks, which we call database migration. In the method proposed previously, it was assumed that we know the sequence of accesses to the system, this is used for database relocation. However, in order to use database migration in a practical environment, it is necessary to detect the access skew. In this paper, we propose a database relocation method which detects access skew from the access information. Moreover, we examine the effectiveness of the proposed method by comparing it with the conventional database-fixed method.
