Big Data: A Survey
In this paper, the authors review the background and state-of-the-art of big data. They first introduce the general background of big data and review related technologies, such as could computing, Internet of Things, data centers, and Hadoop. They then focus on the four phases of the value chain of big data, i.e., data generation, data acquisition, data storage, and data analysis. For each phase, they introduce the general background, discuss the technical challenges, and review the latest advances.
