Abstract: Starting from the numerical associations among business objects, a log-based object association model was presented, in which complex and volatile associations among objects were clearly separated from the inner structures of objects themselves. According to this model, a code generator was designed and implemented to support rapid changes of system behaviors and automatic code generation after requirement changes. Run-time states of business objects and association information among objects were separated as logs from business object information, and with the aid of such logs, flexible traceability among business data could also be conveniently realized. Practical applications have validated the feasibility of this approach.
