The invention discloses a multi-dimension-based role permission management method. The method comprises the following steps of S1: establishing a database, and entering the step S2; S2: allocating a corresponding permission to each role, storing corresponding relationships in an operation function permission table, a management range permission table, a data range permission table and a data security level permission table respectively, endowing each user with a corresponding role, storing the corresponding relationships in a role table, and entering the step S3; and S3: performing user login,and according to corresponding roles in the role table, obtaining corresponding permission ranges in the operation function permission table, the management range permission table, the data range permission table and the data security level permission table. By performing multi-dimension management on role permissions, the problem in application management of different business posts and different permission requirements of data is essentially solved; system permission management work of enterprise application system management personnel is greatly facilitated; and the system data security requirements of users are increased.
