软件体系结构Software Architecture 第三章 软件体系结构风格 Chapter Three Software Architecture Style 本章要点 软件体系结构风格 Software Architecture Style 经典体系结构风格讲解 Illustration on Typical Architecture style 客户/服务器风格 Customer/Server Style 浏览器/服务器风格 Browser/Server Style 新型体系结构风格 New Architecture Style 总结 Summary 软件体系结构风格Software Architecture Style 软件体系结构风格是描述某一特定应用领域中系统组织方式的惯用模式. Software Architecture is to describe system organization normal model for certain application area 体系结构风格定义了一个系统家族,即一个体系结构定义一个词汇表和一组约束.词汇表中包含一些构件和连接件类型,而这组约束指出系统是如何将这些构件和连接件组合起来的. Software Architecture style defines system family, or we may say, one architecture define a vocabulary list and a restriction 体系结构风格反映了领域中众多系统所共有的结构和语义特性,并指导如何将各个模块和子系统有效地组织成一个完整的系统. Software architecture reflects common structure and characters of many system and also integrate every individual model and subsystem into one effective system Three Level Pattern 架构模式(Architectural Pattern) 设计模式(Design Pattern) 代码模式或成例(Coding Pattern OR Idiom) Types of Architeture Pattern From Mud to Structure型 分散系统（Distributed Systems）型 人机互动（Interactive Systems）型 Adaptable Systems型 本章要点 软件体系结构风格 Software Architecture Style 经典体系结构风格讲解 Illustration on Typical Architecture style 客户/服务器风格 Customer/Server Style 浏览器/服务器风格 Browser/Server Style 新型体系结构风格 New Architecture Style 总结 Summary Common Architectural Styles Dataflow Pipes and filters Batch sequential Data-centered Repository Blackboard Virtual Machine Interpreter Rule-based system Call and Return Main program and subroutine OO ( Data abstraction) Layered Independent components Communicating processes Client/server Event systems Implicit invocation 隐式调用 Explicit invocation How can we study Arch.
