The Persistent classes aim to make data persistence easy.
persistent类旨在使数据持久性变得简单。
The CPAN Persistent classes are powerful allies in your search for data persistence solutions.

Before we can use ofy, however, we need to register persistent classes in a static initializer like Photo in Listing 2.
然而，在我们使用ofy之前，我们需要在一个静态的初始化方法中注册持久化类，如清单2的Photo。
In the Persistent classes, the datastore is an abstract storage device, which can be a file or a database, for example.
在persistent类中，数据存储器是抽象存储设备，例如，它可以是文件或数据库。
The Persistent classes will automatically create the necessary functions ($equation->answer(), for example) to access the data members.
Persistent类将自动创建必要的函数（例如，$equation->answer()）来访问数据成员。
Any other program that knows the attributes of our objects can use the same datastore (more on this under "Inheriting from Persistent classes").
任何知道对象属性的其它程序都可以使用同样的数据存储器(这方面的详细信息在“从persistent类继承”中)。
Remember that good design and a clear definition of the attributes are just as important as the Persistent classes in achieving successful data persistence.
请记住，在实现成功的数据持久性时，好的设计和属性的清晰定义与Persistent类同等重要。
It also introduces the BaseEntity and AuditableEntity base classes, from which concrete persistent classes can be extended, depending on whether or not auditing information is required for an object.
还引入了BaseEntity和AuditableEntity基类，可以根据是否需要对象的审计信息，分别从这些基类派生出具体的持久化类。
Persistence classes encapsulate access to your persistent stores, including relational databases, flat files, and object bases.
持久性类封装对持久性存储的访问，包括关系数据库、平面文件和对象库。
Whether these abstractions will be represented as Geronimo classes and objects or as database tables depends primarily on how you're going to use them and how persistent they will be.
将这些抽象的概念表现为geronimo类及对象还是数据库表主要取决于您将如何使用它们，以及它们将持续多久。
The model is made up of five classes, four of which are persistent. The non-persistent OrderSystem class serves as the root of the object model.
这个模型由5个类组成，其中的4个是要持久化的类，非持久化类oradersystem当做这个对象模型的宿主。
The simplest enhancer task does both: it optimizes Native Queries and it adds the Activatable interface to your classes, making sure a persistent object is activated whenever any field is read.
最简单的增强器任务：优化原生查询而且为类增加可激活接口，以确保无论何时读取任何字段，相应的持久化对象都会被激活。
Business logic and any non-persistent data can be implemented completely in partial classes and methods of entities and the data context, or it can be implemented in separate classes.
商务逻辑以及任何非持续性资料则可完全实作在实体的部分类别和方法和资料内容，或可以实作在另外的类别中。
