| Abstract: | This paper analyses the requirements of authoriazation in an office automationsvstem. First we extend the conventional model of authorization in most commercial data-base systems,and then present a multilevel authorization model(MAM model)based onTOHR data model.We edthe paper by discussing the basic concepts about authorizationsubject groups,authorization object clusters as well as authorization type sets in in texto-riented databese management system(FIMS). |
