You use the active record pattern to wrap relational database persistence methods in domain classes.
活动记录模式则可用来在域类内包装关系数据库持久性方法。
The DAO pattern protects your application from being tied to a particular persistence approach.
DAO模式可以保护应用程序，使之不必与特定持久性方法捆绑在一起。
What we have achieved so far is a lean and mean implementation of a DAO pattern which allows the persistence of 'state-only' entities.
到目前为止，我们精简了DAO模式的实现，该实现只能持久化实体的状态。
This structure is an application of the 3-layer pattern, which separates application logic into Presentation, Business, and Integration/Persistence categories.

For instance, with slight modification you can introduce the state pattern with some persistence to keep track of conversational state.
例如，只需稍作修改，就可以为state模式引入持久性，以跟踪会话状态。
In the widely used traditional DAO/Repository pattern, DAOs have the responsibility to perform persistence operations, which are purely behavioral, and entities are supposed to hold state.

Further intelligence automatically constructs high availability messaging, global security, or session persistence as per the pattern definition.
智能进一步根据模式定义自动构建高可用性消息传递、全局安全性或会话持久性。
Probably some people regard changing jobs frequently as a modern living pattern, while I believe if one wants to accomplish something in life, persistence is an essential element?
