  2. 本讲内容 • 网络系统设计模式 • 综合案例分析

  3. Model • Encapsulates application state • Responds to state queries • Exposes application functionality • Notifies views of changes State Change State Query Change Notice • View • Renders the models • Request updates from models • Sends user gestures to Controller • Allows controller to select View • Controller • Define application behavior • Maps user actions to model updates • Select view for response • One for each functionality View Selection User gestures Web Application Architecture: MVC Model
