Abstract

The invention discloses a data processing method and a data processing device for on-line analysis processing. The data processing method for on-line analysis processing comprises the following steps of acquiring data in on-line analysis processing and partitioning the data so as to obtain a plurality of partitions; respectively calculating user numbers of de-weighting counting indexes of the partitions; and adding the obtained user numbers of the de-weighting counting indexes of the partitions so as to obtain the user number of de-weighting counting in the on-line analysis processing. By using the data processing method, the problem that the cost for an internal memory when in on-line analysis processing is high in the prior art is solved, and the effect of reducing the cost for the internal memory when in on-line analysis processing is achieved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data processing method and device for online analysis and processing. Background technique [0002] The deduplication index refers to the number of users such as "visitors", which is a non-accumulative index. When calculating, all the required data needs to be loaded into the memory, and then deduplication is performed, and finally the number of users is obtained. [0003] The non-accumulative index means that the index data cannot be superimposed. Assume that the online analytical processing is partitioned by time, for example, each month is divided into one district. If the number of users recorded in the partition in September is 100, the number of users recorded in the partition in October is 200, then the number of visiting users in the past two months (September and October) may be any value between 200 and 300 after deduplication. The values ​​obtained from the partitions...
