对会话作用域(即在一个会话中存储和维护的数据的上下文)的适当处理是有状态应用程序开发的关键。
Proper handling of session scope — that is, the context of the data being stored and maintained in a session — is key to stateful application development.
术语“作用域”指的是一个上下文，在这个上下文中数据被关联或者存储。
The term scope refers to a context in which data can be associated, or stored.
每种J2EE作用域都有一个上下文，在这个上下文中可以关联(存储)基本类型的数据和对象引用，以供享有同一上下文的其他组件使用。
Each of the J2EE scopes has a context in which primitive data and object references can be associated (stored) for use by other components that share the same context.
为了智能地管理用户数据，必须将其置于上下文中。出于这个原因，我们使用作用域。
In order to intelligently manage user data, we have to contextualize it; and for this we use scopes.
这个标记有助于描述其作用域内的所有数据元素是什么吗？
Does this tag help describe what all data elements in its scope are?
除非将数据源的作用域定义为集群，否则您可利用在单服务器环境中的相同方法，在集群环境中创建数据源。
You create the data source in a clustered environment in the same manner as you do in a single-server environment, except that you define the scope for the data source as cluster.
它简单，而且是JSP数据的默认作用域。
流作用域的持久化上下文对象将流期间加载的数据作为持久化实体来管理并将数据变更缓存为实体的脏状态。
The flow-scoped persistence-context object manages data loaded during the flow as persistent entities, and data changes cached as the entities' dirty states.
但有时，您可能需要减小事务的作用域以获取吞吐量、改善性能并提高数据库的并发性。
However, there may be times when you need to reduce a transaction's scope to gain throughput, improve performance, and increase concurrency in the database.
无论是在期望还是所需的功能方面，数据库包通常具有范围更广的作用域。
Database packages typically have a wide scope, both in terms of expectations and required functions.
资源的作用域(比如jdbc访问接口或者数据源)定义了其在应用服务器环境中的可见性。
A scope for a resource (such as the JDBC provider or data source) defines its visibility in the application server environment.
对于JSP数据坚决使用page作用域。
将application作用域专用于全局数据。
术语作用域指的是被存储数据的上下文(即该数据的“作用域”)；对作用域的适当处理在有状态Web应用程序的设计中处于核心地位。
The term scope refers to the context of stored data (the data's "scope"); and the proper handling of scope is at the heart of stateful Web application design.
实现作用域内当前名称空间声明堆栈的数据结构。
NsStack: a data structure that implements a stack of namespace declarations that are currently in scope.
向提供数据选择的支持bean添加的内容主要是注释；放到conversation作用域时，必须将该类序列化。
The additions to the backing bean to accommodate the data selection are primarily annotations; the class must be serializable when it is placed into the conversation scope.
乍一看来，使用这4种数据类型来存储有作用域的数据是相当直观的。
At first glance, it might seem that using these four data types to store scoped data would be pretty straightforward.
在这4种作用域中，每一种作用域都有一个不同的机制，用于存储并最终访问上下文相关的数据。
Each of the four scopes has a different mechanism for storing and ultimately accessing contextual data.
持久化上下文作用域划定到数据库事务。
图2展示如何利用IntegratedSolutionsConsole的Datasources页面来选择新数据源的作用域。
Figure 2 shows how to use the data sources page of the Integrated Solutions Console to select the scope of a new data source.
关闭，如果做得正确，允许你通过封装数据的作用域链不能由其他人修改使用。
Closures, when done correctly, allow you to encapsulate data through the use of the scope chain that cannot be modified by any other caller.
数组变量的命名同样遵循PHP变量命名约定(参见第9页“变量：数据类型，弱类型，作用域”)。
Array variable names follow the same naming rules as regular PHP variables (see the section "variables: Data Types, Loose Typing, and Scope" on page 9).
