Entity Driven Task Software Framework for EIS

Enterprise information systems are usually reappearance of enterprise business actions. However, surprisingly little research has been done on partition rules and implementation methods of enterprise business in enterprise systems. This paper begins with our presentation that enterprise information system can be abstracted to a scenario in which users could schedule the task suites of controlled entities under enterprise security mechanism. Then a novel framework for enterprise information system, named EDTSF (Entity Driven Task Software Framework), was proposed by means of updating some information system engineering methodology and technologies. The EDTSF can clearly implements enterprise business partition, and can also reduce coupling between data objects and task objects. At the same time, the EDTSF increases flexibility and expansibility of enterprise information systems by expanding service function of data object and reusing the scheduling mechanism at system level.
