Abstract: A thrips control agent in accordance with an embodiment of the present invention is used for plants belonging to family Brassicaceae, family Solanaceae, family Rosaceae, family Cucurbitaceae, family Fabaceae, or family Asteraceae. The thrips control agent contains prohydrojasmon as an active ingredient, so that a negative impact of the thrips control agent on plant growth is suppressed.

Abstract: A data analysis method for analyzing data on a data analysis apparatus having: setting, a plurality of dimension tables each having a first identifier for identifying data to be analyzed and attributes corresponding to the first identifier; setting, a history table having a second identifier associated with each of the first identifiers of the dimension tables, and having attributes corresponding to the second identifier; setting, a relation table for storing attributes relating to the first identifier, the dimension tables having a first dimension table associated with the relation table through the attribute relating to the first identifier; associating, the first identifiers that refers to the first identifier of a first dimension table with the attributes; and processing, a query for the relation table and the first dimension table, and generating a second dimension table.

Abstract: A join query execution method and device include a processor and storage medium. An external data source connected to a data management system by a table function is searched, regarding and joining processing against a join query regarding a search result of the table function and a table managed by the data management system, the joining processing is executed on the search result by a first joining method; a join query execution device determines whether the first joining method is appropriate, by using information acquired by search processing on the external data source; and when it is determined that the first joining method is not appropriate, the join query execution device recognizes a speed of a second joining method to be higher than that of the first joining method and switches the joining method for the joining processing to the second joining method.

Abstract: A data management method employing the results of an analysis of data stored in a storage unit of a computer provided with a processor and a storage unit, wherein the computer generates an analysis data set by selecting data stored in the storage unit, subjects the analysis data set to prescribed data mining, extracts a model from the analysis data set, converts the model into a relational table, and associates the relational table with a dimension table and a history table that have been stored in advance in the storage unit.
