The traditional algorithms for mining association frequent patterns generate conditional sub tables
which costs much runtime and memory space.To solve these problems
a new algorithm FIA(Frequent Iternset Algorithm)is proposed. The FIA algorithm adopts a binary of symbols to compress the store data.The algorithm using logic of symbols to express data in a database
which only after one scan
and establish a binary vector and upper triangular frequent matrix
according to the both to produce a set of frequently.Thereby effectively narrowing the search space
speed up the processing speed.Through analysis showed that
FIA algorithm more effective than Apriori algorithm.
