For the last several decades, the rapid development of information technology and computer performance accelerates generation, transportation and accumulation of digital data, it came to be called "Big Data". In this context, researchers and companies are eager to utilize the data to create new values or manage a wide range of issues, and much focus is being placed on "Data Science" to extract useful information (knowledge) from digital data. Data Science has been developed from several independent fields such as Mathematics/Operations Research, Computer Science, Data Engineering, Visualization and Statistics since 1800s. In addition, Artificial Intelligence converges on this stream recent years. On the other hand, the national projects have been established to utilize data for society with concerns surrounding the security and privacy. In this paper, through detailed analysis on history of this field, processes of development and integration among related fields are discussed as well as comparative aspects between Japan and the United States. This paper also includes a brief discussion of future directions.
