摘要： By introducing the concept of negation into an association rule, the number of combinations of items, serving as candidates of the association rule containing negative items, becomes enormous for mining. The invention sorts out frequent itemsets to be included in an association rule in advance by ensuing its upper bound of confidence satisfying conditions of a confidence and a confidence increment input by an user. Also, by checking a logic product for each bit of a bit string reflecting the presence of each item in the itemset, the combinations of items as candidates are pruned. The pruning of unnecessary combinations is effectively carried out. The number of combinations of the items for compiling association rules is reduced.

摘要： A data relay server connected between a client computer and a database server produces a query message obtained by encrypting a retrieval condition designated by the client computer, and transmits the query message to the database server. The database server encrypts a specific data item which is designated by the retrieval condition and read out from the database, retrieves service information matched with the retrieval condition by encrypted data matching, and replies the service information as a retrieval result to the data relay server.
摘要翻译：连接在客户端计算机和数据库服务器之间的数据中继服务器产生通过加密由客户端计算机指定的检索条件获得的查询消息，并将查询消息发送到数据库服务器。数据库服务器加密由检索条件指定并从数据库读出的特定数据项，通过加密数据匹配检索与检索条件匹配的服务信息，并将服务信息作为检索结果作为检索结果回复给数据中继服务器。

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： 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.

摘要： A stream data processing system restrains the generation of communication traffic in the case of distributing loads by using a plurality of information processing devices. The global query is divided into a plurality of processes. At every divided process, a local query which includes the corresponding process is generated and each local query is set to a query processing device different from each other. In addition, the stream data is transmitted among a plurality of query processing devices in order so as to execute the local query in each query processing device. At this time, the entire stream data does not transmitted among the query processing devices in order. At least a part of the corresponding stream data is stored in a proxy device. When data received from an information processing device located in immediately before does not include the target data of the local query, the query processing device reads the corresponding data from the proxy device and executes the local query.
