Data processing method and data processing device

The invention provides a data processing method and a data processing device. The method comprises the following steps of extracting a plurality of original record data from a use log which includes a plurality of users and corresponds to a plurality of pieces of software according to the preset frequency; performing deduplication processing on the plurality of original record data corresponding to each piece of software so as to eliminate redundant original record data; performing calculation processing on a deduplication processing result so as to determine a statistic analysis value of each piece of software; and storing calculation processing results to a memory according to a specific sequence. By adopting the technical scheme, the redundant data can be filtered away, so that the accurate and efficient statistic analysis on relevant data is realized.
