On the premise of considering basic characteristics of enterprise are the flowing and reengineering of business process, a unified modeling method was put forward for constructing data-centered information system. Based on the core process modeled as transactional workflow, the enterprise was also rendered by the combination of organization model, resources model and relevant data model. Among these models, a man-machine oriented transactional workflow model was provided and analyzed in detail on the aspects as the capability of transactional process and coordination. In order to add more flexibility to the operation model of workflow, a technique based on pull-push model, which contained three ties as Web client, workflow machine implemented on Petri Net and system-enabler was further discussed. As for implementation, the object-oriented method could be applied to design each model to satisfy requirements of system flexibility on the modeling phase. Furthermore, in the framework of distributed object computing technique, the multi-agent technique was employed to improve the flexibility of system.
