步骤3：断开数据库连接。
断开数据库连接。
我选择了一个共同的数据格式，这是很好的支持，并在世纪乐的CF：断开数据集。
I chose for a common data format, which is well supported in Dotnet and the CF: disconnected Dataset.
到达截至日期时，请确保所有用户都完成了当前工作，然后通过关闭数据库服务或从网络断开数据库来断开对服务器的访问。
When the deadline arrives, make sure that all users are finished, then cut access to the server by either shutting down database services or unplugging the database from the network.
据伯奇博士说，一旦这些激光器被断开后，用这种方式记录下来的数据能稳定地保留12年以上。
Once the lasers are switched off, data recorded this way will, according to Dr Birge, remain stable for more than 12 years.
但通过AIR，这些类型的框架现在可以通过连接进行发布和运行，它们同时也拥有一种强大的方式保证在断开连接后依然保存数据变化。
With AIR, these types of frameworks now have a means of being delivered and run with a connection, and a robust means to store data changes while disconnected.
当一个管道驱动的数据传输操作完成时，断开客户端操作完成，重用管道实例给另一个新链接服务。
When a pipe-driven data exchange operation has finished, the completion routine disconnects the client and reuses the pipe instance to serve a new one.
一旦计算机断开对等网络，网络形成的节点随即不复存在，储存在节点上的密钥数据也随之消失。
When a computer is disconnected from the network， the node it formed ceases to exist and any encryption-key data stored there are lost.
在会话中存储数据对象：由于我们已从数据库断开连接，因此需要将联系人数据对象存储在会话中，以便将它用于下一页。
Store the data object in the session: Because we are disconnected from the database, we need to store the contact data object in the session to make it available to the next page.
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.
一旦更新了在前一节讨论的所有数据库配置参数，就需要确保所有应用程序从数据库断开连接。
Once all of the database configuration parameters that we discussed in the previous section are updated, you will need to make sure all applications disconnect from the database.
当你打开一个文件，它不断地保存在内存中，但对于光盘，硬盘，当你断开电源的时候，数据不会丢失。
When you're working on a file, it's saving constantly to RAM but also hopefully to disc, the hard disk so you don't actually lose it if the power goes off.
DataSet也与实际的数据存储断开连接，可以通过一个或多个DataAdapter(每个DataTable一个)来填充它，然后在内存中保存这些数据和所有更改。
The DataSet is also disconnected from the actual data store. It gets filled through one or more DataAdapters (one per DataTable), and then keeps that data and any changes in memory.
Quiesce数据库 ——可以显式地断开所有应用程序的连接，也可以使用这个新的 quiesce 数据库特性。
Quiesce Database - You can explicitly disconnect all applications or you can use this new quiesce database feature.
一些参数设置只有在断开所有应用程序与数据库的连接之后才会生效。
Some of the parameter settings will only be effective after you disconnect all applications from the database in effect.
此后，我们可以断开与数据库的连接，并在本地操作和浏览数据。
We can then disconnect from our database and manipulate and scroll through our data locally.
一旦用户从数据库服务器断开连接，会话将消失。
Once the user disconnects from the database server, the session disappears.
但是在这样做之前，我们先来演示一下断开与数据库的连接然后执行离线连接操作的能力。
But before we do, this, we will demonstrate the ability of being able to disconnect from the database to perform an offline join operation.
该数据返回时，SDO可以随即识别在客户机断开连接时所发生的任何更改。
Upon return of that data, SDO can then recognize any changes that occurred while the client was disconnected.
脱机备份要求所有应用程序断开与数据库的连接，联机备份允许在备份的过程中继续执行事务。
Offline backup requires that all applications disconnect from the database, whereas online backup allows transactions to carry on while backup is in progress.
请求模板告知服务实现响应中需要哪个(已断开连接的)数据对象图子集。
The request template tells the service implementation what (disconnected) sub set of data object graph is required in the response.
其他想要并发访问相同表中的数据的应用程序不需要与数据库断开连接，并且可以继续进行该表中的读或写操作。
Other applications that want to access data in the same table concurrently do not need to disconnect from the database, and are free to pursue read or write operations in that table.
一旦配置了数据适配器，您就可以生成数据集定义了，该数据集将存储您的数据适配器断开连接的结果集。
Once you have configured your data adapter, you can generate the data set definition that will host your data adapter disconnected result sets.
该分析确定已有的数据源在什么地方被断开，并在数据本身中包含内嵌的逻辑。
This is an analysis that determines where existing data sources have broken down and contain embedded logic in the data itself.
在断开连接的数据图形体系结构下，客户机将从数据源检索数据图，对数据图进行变异操作，然后将数据图更改应用回数据源。
Under the disconnected data graphs architecture, a client retrieves a data graph from a data source, mutates the data graph, and can then apply the data graph changes back to the data source.
协议基本上应该知道如何处理连接的建立和断开，以及如何在连接中接收和发送数据。
Basically, a protocol should know how to handle making and losing connections, and receiving and sending data within a connection.
减少数据库开销：sdo的核心是支持断开连接的工作。
Reduced database overhead: at the heart of SDOs is support for disconnected working.
当发生故障时，例如服务器HADB 1失效，那么连接到HADB1的所有用户都要断开到数据库的连接。
When a failure occurs, for example server HADB1 fails, then all users connected to HADB1 are disconnected from the database.
在断开连接的数据图表架构中，客户机从数据源检索数据图表、更改数据图表，然后将这些数据图表更新应用于数据源。
Under the disconnected data graphs architecture, a client retrieves a data graph from a data source, changes the data graph, and can then apply the data graph updates back to the data source.
在SDO中构建了开放式并发支持，允许处理断开连接的数据，而无需要求应用程序实施更改跟踪和冲突检测。
Optimistic concurrency support is built into SDO, allowing disconnected data manipulation without requiring the application to implement change tracking and conflict detection.
