Abstract: The enterprise information system is becoming increasingly complicated. A method based on the enterprise architecture design is proposed in this paper to construct and apply the enterprise architecture model for information from the global perspective. The paper discusses the method’s theoretical basis, construction process, application scenarios and application results. The method not only makes the information system and the service consistency analysis more standard and automatic, but also makes it easier to construct a steady enterprise architecture of information system so as to realize the matching of enterprise’s IT strategy and business strategy, data sharing, module integration, business collaboration, and meet the business requirement for future development.
