摘要： Even when information lifecycle management is applied to management object data of a database management system, inquiry service performance offered by the database management system can be guaranteed. Data arrangement managing system performs data arrangement settings in respect of management object data of the database management system and has a data arrangement setting creating module for determining possible data arrangement candidates and a data arrangement setting exchanging module for transferring the data arrangement candidates to the database management system. In the database management system, in respect of the individual data arrangement candidates transmitted to the database management system, execution profiles of service presupposing the candidates are created which are decided as to whether to satisfy a condition on database performance designated by a user and a narrowing down module narrows down the candidates to only data arrangement candidates satisfying the condition.

摘要： In order to realize a practical data warehouse system with the use of a network in a distributed environment, for example, data collectors for creating/managing each replica of server data for clients shown in FIG. 1 are connected to a network. A data collector holds a data request condition given from a user via a client and negotiates with a server which supplies data according to such resources as a storage unit, a CPU, etc., usable by the data collector, thereby the range and quality of the data for which a replica is to be created can be adjusted. For query processing, a part or the whole of a query from a client is processed with the use of a replica created in the data collector. Queries which cannot be processed with any replica in the data collector are transferred to the server. Because a replica created in the data collector can be used to process a query from a client in such a way, the server load can be reduced.

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.

摘要： A shared-nothing database management system employs a method of adding and removing a database server without significantly affecting the processing performance for accessing a table from a user or an application. A scheduler module creates a schedule which separately handles the addition of a CPU resource and the addition of a storage I/O resource, and a server is added in accordance with the created schedule. A common disk is used to remove a disk at an arbitrary timing. Further, a data region is previously subdivided on the common disk to eliminate a movement of data associated with the addition of a server.

摘要： The present invention aims to dynamically re-configure hosts and storage in a shared-nothing database. In the shared-nothing database, processes 24 to 29 executed in the hosts 11 to 14 access data of a storage device 30. A system manager 70 and a database manager 10 manage the hosts 11 to 14 and the storage device 30. The processes 24 to 29 access one or more disks 51 to 54 of the storage device. To add or reduce the number of the hosts, the processes 24 to 29 are reassigned among the hosts 11 to 14.

摘要： In order to realize a practical data warehouse system with the use of a network in a distributed environment, for example, data collectors (101 and 102) for creating/managing each replica of server data for clients (103 and 104) as shown in FIG. 1 are connected to a network (113). A data collector holds a data request condition given from a user via a client and negotiates with a server (114, 122) which supplies data according to such resources as a storage unit, a CPU, etc. usable by the data collector, thereby the range and quality of the data for which a replica is to be created can be adjusted. For query processing, a part or the whole of a query from a client is processed with the use of a replica (123) created in the data collector. Queries which cannot be processed with any replica in the data collector are transferred to the server. Because a replica created in the data collector can be used to process a query from a client device such a way, the server load can be reduced.

摘要： In order to realize high speed process for grouping the records having the identical values of one or more columns of the input list, the input list is canned, a hash value is generated using a hash function in which a value of the column as the non-vacant partial aggregation of the columns for the grouping is used as the argument, and it is determined whether two or more records having the hash values exist or not. The input list is scanned again and the calculating process of the aggregation columns is immediately executed for the records having the hash value for which it is determined by the first scanning that there is only one record having the identical hash value, the result of such calculating process is output and the records are defined as the input of the ordinary grouping process for the records which are determined to exist as the two or more records.

摘要： A query issue processing method, a query conversion processing method, and a data control processing method are provided for enhancing the efficiency of random sampling processing for use in a database processing system. In query issue processing 2, a query including random sampling processing is issued. In query conversion processing 8, application sequences of random sampling processing and another query processing are exchanged by considering a sampling unit of the random sampling processing. Further, in record control processing 4, random access to a secondary storage device is reduced, thereby enhancing random sampling processing efficiency. Unlike the conventional query conversion processing not considering the sampling unit, the issuance of the query including random sampling processing and performing query conversion by considering the sampling unit allow random sampling to be applied also to a query including aggregation processing, thereby enhancing the efficiency of queries in a wider range. Reduction in the random access to the secondary storage device further enhances that efficiency.
