    A. client-based architecture
    基于客户端的架构
    B. server-based architecture
    基于服务器的体系结构
    C. network architecture
    网络体系结构
    D. client-server architecture
    客户机服务器体系结构

    答案：D
    解析：
    体系结构设计指定了将使用的总体架构和软件和硬件的位置。架构设计是一个非常复杂的过程，通常留给经验丰富的架构设计师和顾问。第一步是将非功能需求细化为更详细的需求，然后使用这些需求来帮助选择要使用的体系结构和将要放置在每个设备上的软件组件。在客户端-服务器体系结构，也决定是否使用双层、三层或多层结构。然后，需求和体系结构设计用于开发硬件和软件规范。有四种主要类型的非功能需求在设计架构中是很重要的。操作要求指定操作环境，系统必须执行和那些可能会随时间而改变。性能要求关注非功能性需求的问题，如响应时间、容量和可靠性。安全要求的能力来保护信息系统的中断和数据丢失，无论是通过故意行为造成。文化和政治要求是具体的国家将使用该系统。
