Research And Application Of Extended RBAC Model

Along with computer technology application day by day broad, the application software complex degree increasingly is also high. How the more reasonable design development software, the more scientific control software does develop the process, oneself after becomes the topic which the people widely pay attention. Software reuse is a feasible method for enhancing the software production efficiency and quality. But in very long period of time, sofeware reuse in the whole to the software industry influence not entirely as desired. The people always hoped can obtain the general as far as possible high component; its applicable scope also should as far as possible broad. But the high requirement has been able to cause the technical complexity too to be strong, the implementation difficulty is big, the application foreground is not optimistic. The rich application project knowledge is beneficial in obtains the demand terms of an agreement, the design, the implementation and so on may duplicate use the information, is advantageous for the domain project each phase abstract. Therefore, if we will turn round with the research work mainly concentrate in some familiar specific domain, will make every effort to develop in this domain turns round with the high domain component, then will from now on develop similar or time the close system in this domain, might concentrate the energy in on each system unique ingredient, thus will reduce the development cost, will improve the development quality and the efficiency. The component technology isolates clearly the component from the system logic, uses for to develop the complex system, moreover causes the system the construction cost to be lower, the stability is better, and favors the system the safeguarding. The software turns round with with technical the and so on Internet development, causes the more and more many different domains expert to participate in the component the development, the test, large-scale may duplicate possibly use the component base the existence into. The workflow is aims at in the work to have a concept which the fixed routine the conventional activity proposed. Through will work the activity to resolve the definition good task/role, the role, the rule and the process carries on executing and the monitoring, achieves the enhancement production organization level and the working efficiency target. This topic research aim is carries on the expansion to the RBAC model, forms the time sensitive RBAC model and the resource sensitive RBAC model. And applies it in the workflow in the system, in the use office automation system archives past confirm the model the feasibility, finally uses may turn round with the reusable component, the method analysis, manufactures the component.
