Abstract

The invention provides a data filtering system and method, wherein the data filtering system comprises: an extracting unit for extracting property characteristic of source data and sending it to a selecting unit; the selecting unit for selecting at least one property characteristic based on which data filtering is performed and for sending the selected property characteristic to a filtering condition generating unit; the filtering condition generating unit which, according to the selected at least one property characteristic, generates at least one filtering module that corresponds to the at least one property characteristic respectively and combines the at least one filtering module to generate filtering conditions; a data filter analysis unit which performs the filtering on source data according to the filtering conditions to thereby generate target data. With the invention, it is ensured that when characteristic of data changes, filtering modules can be recombined freely so as to adapt to the change of data characteristic efficiently.
