Enterprise data management method and system based on big data

The invention is suitable for the technical field of enterprise data management, and particularly relates to an enterprise data management method and system based on big data, and the method comprises the steps: S100: collecting production data of an enterprise, searching attributes, traversing numbers of the production data through employing a preset attribute number table, and masking the production data based on the numbers; and S200, creating a main node, classifying the production data with the numbers into the main node, and linking a plurality of groups of sub-nodes into the main node. By constructing the main node, the sub-nodes and the snowflake model, normal calling of the production data is ensured while the production data is stored, a user can only call the production data within the authority of the user by constructing the verification distribution chain, the possibility of leakage of the production data is greatly reduced, independent access control over the snowflake model is supported, and t
