  In the broadest sense, Hibernate categorizes types into two groups:

    Value types

    Entity types

2.1.1. Value types

  Value types are further classified into three sub-categories:

  Basic type        基本类型

    in mapping the Contact table, all attributes except for name would be basic types. Basic types are discussed in detail in Basic Types

  Embeddable types     对象/包装类型    

    the name attribute is an example of an embeddable type, which is discussed in details in Embeddable Types

  Collection types    集合类型

    although not featured in the aforementioned example, collection types are also a distinct category among value types. Collection types are further discussed in Collections
