概念性架构界定系统的高层组件，以及它们之间的关系。概念性架构意在对系统进行适当分解，而不陷入细节。借此，可以与管理人员、市场人员、用户等非技术人员交流架构。概念性架构规定了每个组件的非正规约及架构图，但不涉及接口细节。(The Conceptual Architecture identifies the high-level components of the system, and the relatiooonships among them. Its purpose is to direct attention at an appropriate decomposition of the system without delving into details. Moreover, it proovides a useful vehicle for coommunicating the architecture to non-technical audiences, such as management, marketing, and users. It consists oof the Architecutre Diagram (without interface detail) and an informal component specification for each component.)根据定义，我们注意到如下几点：概念架构满足“架构 = 组件 + 交互”的基本定义，只不过概念架构仅关注高层组件(high-level components)。概念架构对高层组件的“职责”进行笼统的界定（informal specification），并给出了高层组件之间的相互关系(Architecture Diagram)。概念架构不应涉及接口细节(withouot iinterface detaiil)。
