Title:

A flow intensive device and a method

Document Type and Number:

Japanese Patent JP6021111

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a flow aggregation device that accelerates a search function (slice function) of any dimension combination of large-scale multi- dimensional data.SOLUTION: A flow aggregation device according to the present invention is characterized as follows: a unique member is stored every dimension in a dimension member table every dimension in a multidimensional attribute table; multidimensional member information is unified and stored in a member index conversion table; the member index conversion table is referred and a member index to the member is acquired; and a member index data index conversion table is created from the data index of the data table and the acquired member index. The member index and the data index are acquired from the member index data index conversion table and converted into a single data train from the data index. A wavelet tree is created from the data train, and a search wavelet tree DB is created which comprises the combination of the member index, the data index and the wavelet tree.
