Abstract

With the rapid development of technology, we have entered the era of big data. Therefore, the safe and effective handling of abundant amounts of data is essential. This paper analyzes and lists some commonly used data storage systems and encoding techniques and elaborates on the encoding and decoding process of one of them, namely EVENODD Code, which is widely used in distributed storage systems. At the same time, this article briefly discusses the possibility of improving the EVENODD Code. The original traditional EVENODD Code encoding can recover data with up to two block failures, but the computation process is more complex than that of multi-replica technology. As a result, it is less computationally efficient than multi-replica technology. The text briefly mentions the potential for enhancing the efficiency of data operations with the EVENODD Code, which could make it the optimal choice for large-scale, highly reliable applications such as cloud storage and media streaming systems.
