我们使用一个实验室计算机系统的签出和保留应用模型的示例，首先编写从数据库访问应用程序数据所需的最简单的代码。
Using a sample checkout and reservation application model for lab computer systems, we start with the most simplistic code required to access application data from the database.
存储于文件系统的应用程序数据应当在每个集群服务器中保存一致。
Application data stored on files system should be consistently kept in each cluster server.
应用程序数据完整的副本可以在远程系统上快速地、轻松地重新联机。
A complete copy of application data can be quickly and easily brought back online on a remote system.
尽管数据库系统这么好，但是如果不把非活动的旧数据与活动的当前应用程序数据隔离开，应用程序的性能最终会恶化。
However good the database system is, if there is no provision for separating old and inactive data from current, active application data, application performance will eventually deteriorate.
Load：将源系统中的数据加载到应用程序数据库。
Load: data from the source system is loaded into the application database.
简单地说，MIDP记录管理系统（RMS）提供了一种跨多个MIDlet 调用持久性地存储应用程序数据的手段。
Put simply, the MIDP Record Management System (RMS) provides a means to store application data that persists across invocations of a MIDlet.
管理员可能犯的最严重错误就是把服务器的所有资源如操作系统、第三方应用程序、页面空间以及应用程序数据等均置于单个卷组中。
The worst mistake an administrator can make is to put all of a server's resources—operating system, third-party applications, paging space, and application data—within a single volume group.
分配给ContentStore的数据库可能是与其他系统或应用程序数据分享的。
Databases allocated to Content Store might be Shared with other system or application data.
如果有特殊的应用程序数据类型(可能是属于您公司的内容管理系统特有的DTD或XSD)，可以在EncryptedData元素的Type属性里指定它们。
If you have special application data types (perhaps your own DTDs or XSDs that belong to your company's content management system), you can specify them in the type attribute of EncryptedData element.
备份实例和应用程序数据库，并备份实例和应用程序定义，以便在出现硬件和其他系统故障之后，能够快速恢复实例和应用程序。
Backing up the instance and application databases and backing up instance and application definitions so that you can quickly restore instances and application after hardware or other system failures.
在该工具下，可以管理、分析与重用程序数据库中的任何构件，也可以快速提取程序数据库中的任一构件或生成新系统的源代码。
In the tool, we can manage, analyse and reuse any components in the program database and rapidly extract source code of any components or construct the program code of a new system.
即使在应用程序关闭之后，系统数据或应用程序数据也可能暂时处于不可预知状态。
System or application data might be left in an unpredictable state temporarily or even after an application has been shut down.
常见的实现方式是在并行文件系统上层再加入一个可以获取并行程序数据访问模式的层次—并行I/O库。
The common implementation is just adding an I/O library between the applications and the file system to acquire the access pattern of parallel applications.
