Data management system and method based on risk map

The invention discloses a data governance system and method based on a risk map, and the system comprises a construction module which is used for constructing the risk map based on risk knowledge, risk information and risk data; and a governance module which is used for processing the to-be-governed data according to the constructed risk map. According to the method, a data management mechanism is formed by designing a data, information and knowledge layered graph and combining graph combination rules between data (data classes and class rules) and information (information classes and class rules) through graph constraint rules of a knowledge layer to an information layer and graph constraint rules of the information layer to a data layer. Morevoer, high-degree unification of business governance and data governance is formed, and a direction can be provided for better governance cognition, so that a real target of data governance, namely business innovation, is realized. 本发明公开一种基于风险图谱的数据治理系统及方法，其中涉及的一种基于风险图谱的
