The present invention relates to a data compression and decompression system and method for lossless compressing digital data. In one preferred embodiment, the method for handling a data stream having a number of data objects comprising a step of performing a compressing process on a data object based on a compression based value to obtain at least one compressed data result, wherein the data object is considered as one numerical value. The device for handling the data stream comprising a compression means for compressing the data objects according to a compression base value. In another preferred embodiment, the method for handling data having a number of data objects comprising a step of performing a compressing process on a data object by obtaining a compression code for the data object according to a compression coding table, wherein the data object is considered as one numerical value. The device for handling a data stream comprising a compression means for compressing the data objects according to a compression coding table.
