Scientific data center system of Chinese Academy of Sciences: practices and prospects

Abstract

Scientific data have become a basic and strategic resource for innovation and development. As an important carrier of scientific data for long-term preservation and sharing, scientific data centers play an increasingly significant role in supporting the development of scientific and technological innovation. Based on more than 40 years of scientific database development and three years of active exploration, by the end of 2021, CAS had built a scientific data center system of "one general center, 18 disciplinary centers and 13 institutional centers". The total amount of data resources is about 100 PB, basically realizing the normal operation and service of the scientific data center system, and serving as a strong support for scientific and technological innovation in the era of big data. In the future, it will further optimize and improve the layout of the scientific data center system, continuously promote the archiving of scientific data resources, create a series of scientific data brands, develop an innovative environment of data intelligence, and support integrative scientific innovation under the new paradigm.
