Compliance to both abstract and concrete syntax 抽象句法和混合句法规范标准
"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。
