微软应用软件架构设计指南2.0 三种常见的定义(一) Software architecture encompasses the set of significant decisions about the organization of a software system including Selection of the structural elements and their interfaces by which the system is composed Behavior as specified in collaboration among those elements Composition of these structural and behavioral elements into larger subsystems Architectural style that guides this organization Software architecture also involves functionality, usability, resilience, performance, reuse, comprehensibility, economic and technology constraints, tradeoffs and aesthetic concerns
微软应用软件架构设计指南2.0 • 三种常见的定义（一） “Software architecture encompasses the set of significant decisions about the organization of a software system including: Selection of the structural elements and their interfaces by which the system is composed. Behavior as specified in collaboration among those elements. Composition of these structural and behavioral elements into larger subsystems. Architectural style that guides this organization. Software architecture also involves functionality, usability, resilience, performance, reuse, comprehensibility, economic and technology constraints, tradeoffs and aesthetic concerns
微软应用软件架构设计指南2.0 种定义(二) The highest-level breakdown of a system into its parts The decisions that are hard to change There are multiple architectures in a system What is architecturally significant can change over a systems lifetime In the end architecture boils down to whatever the important stuff is
微软应用软件架构设计指南2.0 • 三种定义（二） The highest-level breakdown of a system into its parts. The decisions that are hard to change. There are multiple architectures in a system. What is architecturally significant can change over a system’s lifetime. In the end, architecture boils down to whatever the important stuff is
微软应用软件架构设计指南2.0 三种定义(三) The software architecture of a program or computing system is the structure or structures of the system, which comprise software elements, the externally visible properties of those elements, and the relationships among them. Architecture is concerned with the public side of interfaces; private details of elements- details having to do solely with internal implementation -are not architectural
