保存添加了对象类的组实体类型配置；实体类型配置的对象类显示在图29中。
Save the Group entity type configuration with the added object classes; the configured object classes for the entity type are shown in figure 29.
这些类型可能为实体类本身，或是仅包装实体类中的特定字段以进行远程处理的特殊类。
Those types may be the entity classes themselves, or special classes that wrap only certain fields from the entity classes for remoting.
实现此隔离的一种方式是，将自跟踪实体类型与模型分离，并将用于生成实体类型的模板移动到单独的类库中。
One way to achieve this isolation is to separate the self-tracking entity types from the model and move the template that generates the entity types into a separate class library.
特性的基类，这些特性定义如何将对象层中的类型映射到概念模型中的实体类型和复杂类型。
Base class for attributes that define how properties of types in the object layer are mapped to the properties of entity types or complex types in the conceptual model.
由此强类型的属性将被加到实体类中。
Strongly-typed properties will be added to the entity classes based on this.
一个特性，指示类表示实体类型。
