The invention discloses data authority database middleware based on field tagging. The data authority database middleware comprises a definition layer and a driving layer, wherein the definition layer is used for defining a data table on a management interface, including defining a table name, a table structure and each field attribute of the data table, defining one data table as an object class, and defining table fields as class attributes; the driving layer comprises a data layer and a permission layer, the data layer generates a unique attribute index for the data in the data table and is used for realizing data synchronization, and the permission layer is used for matching user permission and filtering data without access. According to the method, in the field of data management, by introducing a data tagging technology and marking and classifying data, rapid data retrieval and authorization are achieved, the safety and efficiency of the system are improved, and meanwhile the complexity of development a
