Abstract: Data is a product between subjectivity and objectivity, and is the representation of the subject to the object. Due to the complexity of human beings and the diversity of things, data cannot fully characterize the objective world, resulting in a split between the subject and the object, and causing alienation. The trend of digitalization of modern technology and the scientization of technology have made modern technology present more and more powerful information characteristics, that is, the construction characteristic of information on physical energy. Big data technology promotes the generation, production and reproduction of massive data, triggers a revolution in data structure and data analysis technology, and drives data from representation to practice. The practical ability of data in the dual dimensions of virtuality and reality has bridged the rift between subject and object in data representation, and unified the datamation of objects and the materialization of data. Mankind is being liberated from “dependence on things”, entering the information civilization society of comprehensive and free development.
