Anyway, this section talks about UML and class diagrams, inheritance, polymorphism, encapsulation... things they should have shown you in the beginning.
总之，该部分讨论了UML和类图、继承、多态性、封装…一些应该在开头为您介绍的东西。
"Table per Concrete Class using implicit Polymorphism" is not recommended due to its verbose configurations, complex association syntax using "any" element and potentially dangerous implicit queries.
“使用隐式多态实现每个具体类一张表”这种做法并不推荐，因为其配置过于繁缛、使用“any”元素的复杂关联语法和隐式查询的潜在危险性。
A mechanism for treating different implementations as logically "the same kind of thing" - usually polymorphism is implemented via interface implementation and class inheritance.
l一种逻辑上做相同事情，但却有不同实现的机制。我们通常称之为多态机制。
Using the encapsulation, inheritance and polymorphism of OOP, a foundation class library of small satellite software is designed, the detail design of all base classes is introduced.
利用OOP的封装性、继承性和多态性，设计小卫星软件的基本类库，介绍各个基本类的具体设计思想。
All you need to do is upcast from the derived class and never look back to see what exact type of object you're dealing with. Everything is handled through polymorphism.
你只需要将对象上传转化为基类对象不需要知道额外的信息，而这些都是通过多态实现的。
