实体驱动业务的企业信息系统软件框架

Entity-driven Task Software Framework for EIS

现代企业日益强化企业信息系统的开放性、可重用性和可伸缩性。本文针对当前企业信息系统研发中的一些问题,在将企业信息系统可被抽象表示为"用户在安全控制下对受控实体的一组业务集合的调度"的基础上,提出了实体驱动业务的信息系统软件框架EDTISF。重点讨论了EDTISF如何以"受控实体"来实现企业业务的确切划分,如何通过独立的数据对象来降低业务及其处理数据的耦合度,以及如何在应用层的级别上实现业务调度机制的重用等问题。

In this paper, we present that EIS （Enterprise information systems） can be abstracted to a scenario in which users could schedule the task suites of controlled entities under enterprise security mechanism, and propose a novel Entity Driven Task Software Framework （EDTSF） for EIS. Based on existing hierarchical information system architectures, the EDTSF could clearly implements enterprise business partition, reduces coupling between data objects and tasks; it also increases flexibility and expansibility of the EIS by expanding service function of data object and reusing the scheduling mechanism at system level. We have noticed that little research has been done on the partition rules and methods of enterprise business. The EDTSF is a new software framework and its application results show that the EDTSF is an effective approach to analyzing, designing and implementing EIS.
