Abstract: At present, with the rapid development of network technology and information technology, the number of data information has also exploded, indicating that we are entering the era of big data. In the big data environment, the number of data is massive, and their types become more complex and diversified. Library's digital resource also has the characteristics of big data, while some scattered data information basically has no value for the library, and the digital resource integration and the formation of big data have greater value. This paper analyzed the digital resource integration model in big data environment, and expounded the construction process of digital resource integration platform, hoping to ensure the further improvement of library service level through the effective combination of digital resource and promote the development of big data research in library and information work.
