摘要： A database management system has a plurality of database servers and data can be transferred between them by partitioning a data area into small areas and altering allocation of the small areas to the database servers. After altering the configuration, there occurs degradation in processing speed that accompanies re-creation of the index. If this problem is solved by using conventional techniques, noticeable degradation in processing speed will occur to a specific query at the time of a steady state operation. Accordingly, an index created for each of the small areas and an index to all of the small areas are allocated to the database server and used in combination.
摘要翻译：数据库管理系统具有多个数据库服务器，并且可以通过将数据区域划分成小区域并且将小区域的分配改变到数据库服务器来在数据库服务器之间传送数据。改变配置后，伴随重新创建索引的处理速度降低。如果通过使用常规技术解决了这个问题，则在稳态操作时，特定查询将发生处理速度的显着降级。因此，为每个小区域创建的索引和对所有小区域的索引被分配给数据库服务器并组合使用。

摘要： Provided is a database system in which sorting of query results is sped up. The database system stores storage location information in which storage locations of the pieces of data are recorded in a given order. When there is no second task, which is executed based on data that is fetched in a first task, whether every piece of data requested in a third task, which is executed before the first task, has been fetched is determined. In the case where every piece of data requested in the third task has been fetched, data fetched in the first task is output. In the case where some of the data requested in the third task has not been fetched, data fetched in the first task is kept in a temporary buffer until every piece of data requested in the third task is fetched, and then output.
