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。

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。
