This business object encapsulates the Notes document in a private instance variable inherited from the BOEntity class, so any direct access to this document and its items is prevented.

而这个业务对象在从boentity类继承的一个私有实例变量中封装Notes文档，这样可以保护任何对该文档及其项的直接访问。

In this example, a private String attribute can also be declared in derived business object classes, called dbName, with the name of the appropriate database.

在这个例子中，还可以使用适当的数据库名，在称为dbName 的派生业务对象类中声明私有String属性。
