Under the object-oriented design scheme of information systems, the time-consuming calculation of the derived attribute values is often pre-scheduled due to the application domain requirement. However, in this approach, the function of the persistent objects, in the model layer of the MVC model, deeply depends upon the requirement of the upper domain application view. This degrades the independence of the persistent objects, and the maintainability of the application system. To resolve this problem, this paper proposes a design methodology to calculate the derived attribute values in real-time. Concretely, the proposed method adopts the autonomous objects and difference calculation of time-consuming derived attribute values. The proposed approach simplifies the design process of the higher layer of information systems.
