Poonam Bonde, Sachin Barahate · Journal of Emerging Technologies and Innovative Research · 2017
Due to rapidly increasing size of data which comes from different heterogenous sources, storage, maintenance, processing & real time transfer of big data is becoming a challenging task. Many times data files contain irrelevant and redundant data which can be removed to reduce size of file manageable. Various techniques to achieve this task are called compression techniques. These techniques can be utilized to text, image, audio, video etc data. Compressed data not only increases transfer speed but also improves knowledge discovery as well as processing time.
