摘 要：简述了应用架构的定义、内容、定位和作用。通过 U/C 矩阵法和差距分析法，根据业务域导出应用系统域，对应用系统域内的目标应用系统提出了以业务需求为导向的建设目标；从业务事项和业务数据入手，提出了目标应用系统应覆盖的主要业务功能；基于目标应用系统边界，通过分析相关业务流程在应用系统间的流转关系，确定了目标应用系统间的集成关系，给出了应用系统间交互的核心业务信息，为应用系统的规范化建设提供了依据。

Abstract：The definition，content，positioning and role of the application architecture are briefly described. Through the U/C matrix method and the gap analysis method，the application system domain is derived according to the service domain，and the business application-oriented construction target is proposed for the target application system in the application system domain. The target application system is proposed based on business matters and business data. The main business functions that should be covered are based on the boundary of the target application system. By analyzing the flow relationship between the relevant business processes in the application system，the integration relationship between the target application systems is determined，and the core business information of the interaction between the application systems is given. The basis for the standardization of the system is provided.
Keywords：enterprise architecture；application architecture；U/C matrix method；gap analysis
