在那种情况下，因为池管理器预先在启动时创建连接对象，所以，J2EE组件可以使用连接对象，而不会导致数据库资源管理器上的系统开销。
In that situation, a J2EE component can use connection objects without causing overheads on the database resource manager, since a pool manager creates the connection objects up front, at startup.
当一个EJB组件想访问数据库、消息队列服务器或者其它一些事务性资源时，它需要到资源管理器的连接(通常是使用JNDI)。
When an EJB component wants to access a database, a message queue server, or some other transactional resource, it acquires a connection to the resource manager (usually by using JNDI).
根据属性之间的通信或连接，属性代理然后将接收的数据提供给其他组件的相应操作。
Depending on the connections or wires between components, the property broker then feeds the received data into the appropriate actions of other components.
图1显示了应用程序客户机或组件如何处理由一个或多个数据中介服务(如这里显示的JDBC中介)返回的断开连接的数据图。
Figure 1 shows how application clients or components work with disconnected data graphs returned by one or more data mediator services, such as the JDBC mediator shown here.
当组件被松散耦合或彼此连接时，它们可以通过其属性将数据发送到属性代理，后者将为组件之间的通信提供方便。
When components are loosely coupled or wired with each other, they can send data through their properties to the property broker, which facilitates the communication between components.
本例中的EJB组件使用JNDI查询来确定数据库连接池资源的位置。
The EJB component in this example USES a JNDI lookup to locate the database connection pool resource.
它们可以从那里连接到任何数据相关的组件，就好像从ado.net获取数据一般。
From there, they can be connected to any of the data-aware components just as if they were getting their data from ADO.NET.
因此可以在拥有源需求和目标性能的组件和数据源之间创建一个依赖连接，如清单25所示。
A dependency link can therefore be created between the component and the datasource unit that holds the source requirement and the target capability, as shown in Listing 25.
对于LWWCM的连接标签，可使用联邦内容组件和JSP组件来检索和发布存储在CM中的数据。
With LWWCM's connect tags, the federated content component and the JSP component it's possible to retrieve and publish data stored in CM.
在后端，数据模型与属性代理连接起来，以将更改传递给数据模型中的值，并监听来自其他组件视图的更改。
On the backend, the data model is coupled with the property broker to broadcast changes to values in the data model and to listen for changes imposed from other component views.
Borland DataProvider为开发人员提供了一个ADO.NET接口，其中包含了对设计时存活数据的支持，以及仅通过单一组件连接到不同数据库的能力。
The Borland data Provider offers an ADO.NET interface for the developer with support for live data at design time, and the ability to connect to different database with just one set of components.
Borland DataProvider中提供了一组组件(其前缀为Bdp)，它们可以连接到任何支持的数据库上，可以只通过修改连接字符串来实现连接的切换。
The Borland data Provider comes with one set of components (with the Bdp prefix) that can connect to any of the supported databases, and can switch just by changing the connection string.
