This invention discloses a method for managing module under grading. The method includes: (a) Each module is set to correspond to a managed target, and each managed target has a group of managing commands including all supporting command; (b) All managed targets form a tree shaped managing structure according to registering relationship, wherein the registering managed target is a lower graded managed target, the registered managed target is a upper graded managed target, the uppermost graded managed target is a root managed target. (c) The root managed target receives external managing commands and sends them directly to the objected managed target specified in the managing commands, the object managed target processes the commands and returns back the result of process. |
