The first JSP, Welcome.jsp, occupies both the presentation layer and the data layer by using the JSTL SQL library to issue an SQL query from the page.
第一个JSP，即Welcome.jsp，使用JSTLSQL库从该页面发出一个 SQL查询，因而同时占据了表示层和数据层。
Most applications, however, fit well with the traditional "funnel threading" model (applications spend more time processing data and building the presentation layer than they do retrieving the data).
但是，大多数应用程序都很适合传统的“漏斗线程”(funnel threading)模型（应用程序比检索数据花费更多的时间去处理数据和构建表示层）。
Tune in then to learn how custom tags can facilitate the separation between presentation and business logic, while also letting you incorporate dynamic data into the presentation layer.
学习自定义标记如何促进表示和业务逻辑之间的分离，同时还让您可以将动态数据合并到表示层。
Model refers to your data, View to your presentation layer, and Controller refers to the application or business logic.
模型指数据，视图指表示层，而控制器指应用程序逻辑或业务逻辑。

Typical Web services employ a remote presentation paradigm, meaning all view logic executes on the client, whereas the application logic and the data layer (controller and model) reside on the server.
典型的Web服务使用远程表示范例，这意味着所有的视图逻辑在客户机上执行，而应用程序逻辑和数据层(控制器和模型)则驻留于服务器上。
The application presentation layer is composed of JSPs, servlets, or portlets that get the program data from the back-end (or business logic) and create the layout HTML (or another markup language).
应用程序表示层由jsp、servlet或portlet组成，它们从后端(或业务逻辑)获取程序数据，然后创建布局HTML(或其它标记语言)。
You can use LiveCycle Designer to combine XML schema and the Adobe PDF presentation layer into an XML Data Package (XDP), which creates intelligent, actionable forms.
您可以使用LiveCycleDesigner把XMLschema和AdobePDF表示层结合为 XMLDataPackage（XDP），它创建智能的、具有行为能力（actionable）的表单。
