Database preprocessing is very important to utilize memory usage, compression is one of the preprocessing needed to reduce the memory required to store and load data for processing, the method of compression introduced in this paper was tested, by using proposed examples to show the effect of repetition in database, as well as the size of database, the results showed that as the repetition increased the compression ratio will be increased. The compression is one of the important activities for data preprocessing before implementing data mining.
