In this paper, the authors see any type of data files of any size character by character, they notice that there are many recurrence pattern exhibits in it. A data compression technique takes the advantage of such repetitive sequence of data in order to provide a potential cost saving associated with transmitting less amount of data and reduces storage. There are several data compression techniques available which are used for efficient transmission and storage of the data with less memory space. In this paper, they have proposed a two stage data compression algorithm that is OLZWH which uses the Optimality of Lempel-Ziv-Welch (OLZW) and adaptive Huffman coding. With this proposed algorithm, the data compression ratios are compared with existing compression algorithm for different data sizes.
