上述架构模式的对比 下表格总结了各架构模式的优缺点

分层模式用于对结构化设计的软件进行层次拆解，每个层次为独立的抽象，为其上层抽象提供服务。 系统通常被拆分为以下四个层次： 表示层（也称为 UI 层） 应用层（也称为服务层） 业务逻辑层（也称为领域层） 数据访问层（也称为持久化层）

客户端／服务器模式由两个部分构成：一个服务器与多个客户端。服务器组件同时为多个客户端组件提供服务。客户端向服务器发启服务请求，服务器将相应服务信息回应给客户端。此外，服务器持续监听来自客户端的请求。 使用场景 电子邮件、文件共享及银行业务等在线应用

主／从模式由两个部分构成：主设备与从设备。主服务组件将作业分发给多个从设备组件，并根据这些从设备反馈的结果，计算生成最终结果。 使用场景 数据库复制，主数据库被认定为权威数据源，各从数据库与主数据保持同步 在计算机系统中通过总线互连的各设备（包括主设备与从设备）

管道／过滤器模式用于构造用于生成及处理数据流的系统。每个处理过程都封装在过滤器（filter）组件之中，要处理的数据通过 管道(pips) 进行投递。管道同时用于作为 过滤器（filter） 间的缓冲及同步。

代理模式用于在结构化系统中对组件解耦。系统内各组件间采用远过程调用（remote service invocations）的方式交互。代理（Broker）组件充当组件间通讯的协调角色。 提供服务的组件将其能力（服务以及特性）发布给代理，客户端均向代理请求服务，由代理将请求重定向到先前已发布过对应服务的组件进行处理。

对等模式中的组件称之为对等体（peer），对等体既作为向其他对等体请求服务的客户端，同时也做为响应其他对等体请求的服务端。对等体可以在运行过程中动态地改变其角色，即，既可以单独做为客户端或服务端运行，又可同时作为客户端与服务端运行。

事件总线模式应用于事件处理，主要由四个组件构成：事件源（event source），事件侦听者（event listener），通道（Channel）以及总线（event bus）。 事件源将消息发布到总线的特定通道，侦听者订阅相应的通道，事件源所发布的消息经通道通告给订阅通道的侦听者。

模型／视图／控制器模式（简称 MVC 模式）将交互式应用程序拆分为三个部分： 模型（model） – 包含核心功能及数据 视图（view） – 呈现信息给用户（通过有多个视图） 控制器（controller） – 处理用户的输入操作

黑板模式适用于 无预知确定解决策略 的问题，主要由三个组件构成： 黑板（blackboard） – 用于存储解空间对象的结构化全局内存 知识（knowledge）源 – 能自表意的专用模块 控制（control）组件 – 选择、配置与执行的模块

解析器模式用于设计语言的解析程序，主要用于指定评估程序代码行，即解析出特定语言的语句与表达式，其核心思想是为语言的每个符号定义相应的类。 使用场景 SQL 等数据库查询语言 通讯协议描述语言

For me, it matters that we drive technology as an equalizing force, as an enabler for everyone around the world. Which is why I do want Google to see, push, and invest more in making sure computing is more accessible, connectivity is more accessible.

Becoming an Olympian is the ultimate reward for any athlete.

The full retirement age is 67 and the lifespan is 80, so when they first conceived Social Security, they didn't think they were going to be paying benefits for 13-15 years. That's one of the reasons why this pyramid scheme isn't working.

There are constant challenges in the drawing process, especially in a period piece, and therein lay the fun.

The clothes are not making me... If I like it, that's all that matters...It's not about the clothes. It's about how I am as a person and how confident I am.

When I was in school, martial arts made you a dork, and I became self-conscious that I was too masculine. I was a 16-year-old girl with ringworm and cauliflower ears. People made fun of my arms and called me 'Miss Man.' It wasn't until I got older that I realized: These people are idiots. I'm fabulous.

I'm not a DJ, I don't know how to scratch and I don't know how to mix, but I do know how to party. One of my jobs is actually to travel the world and party.

Those green eyes mocked her and the ass leaned into her blade as if daring her to slice him.

With historicals, the research is half the fun. Contemporaries are especially easy. People are right out there in front of you; you meet them every day. You can concentrate wholly on the story and characters.

I hate science fiction.

In composing, as a general rule, run your pen through every other word you have written; you have no idea what vigor it will give your style.

In the midst of overwhelming noise and distraction the voice of story is calling us to remember our true selves.

Rebellion never goes without consequences.

Nobody cares. You shouldn't either.

When I was growing up in Chicago, my family and I used to go to a local chain, Hackney's, for burgers and their French fried onion loaf. I probably haven't been to one in 25 years, and yet, I once saw Donald Trump from behind in an office building and the first thing that flashed in my mind was his hair looked like that onion loaf.

I'd have to say, for me, as a child, my favorite memories were always centered around Christmas time. It always seemed like no matter how much money my parents had or didn't have, we got completely spoiled rotten. There were always presents under the tree, and we always did special things, like hide elves around the house.

I believe we can all come together, because if you take away the labels, you realize we’re far more alike than we are different.

I love Cleveland, and I love going back home. That's where my family is. That's where my roots are.

For liberals, generally speaking, honoring procedures - means - is the core of what being 'principled' means. For conservatives, fighting for the right outcome - ends - even at the expense of procedural nicety, is what being 'principled' means.

When I was in office the fundraising was done by the party treasurers.

From the year of his birth in 1914 until the outbreak of war in 1941, my father lived in a mostly white, mostly working-class, mostly Irish Catholic neighborhood in Brooklyn, New York.

Where your pleasure is, there is your treasure: where your treasure, there your heart; where your heart, there your happiness

I can't even look at daily comic strips. And I hate sitcoms because they don't seem like real people to me: they're props that often say horrible things to each other, which I don't find funny. I have to feel like they're real people.

I can write, He floated up to the ceiling, and a baby rabbit came out of his pocket, grew wings, and flew away. And you will believe that it really happened. That's magic, isn't it?
