 The <code>AttributeOverride</code> annotation is used to
  override the mapping of a <A HREF="../../javax/persistence/Basic.html" title="annotation in javax.persistence"><CODE>Basic</CODE></A> (whether explicit or
  default) property or field or Id property or field.

  <p> The <code>AttributeOverride</code> annotation may be
  applied to an entity that extends a mapped superclass or to
  an embedded field or property to override a basic mapping
  defined by the mapped superclass or embeddable class. If the
  <code>AttributeOverride</code> annotation is not specified,
  the column is mapped the same as in the original mapping.

  <pre>
  <p> Example:

    &#064;MappedSuperclass
    public class Employee {
        &#064;Id protected Integer id;
        &#064;Version protected Integer version;
        protected String address;
        public Integer getId() { ... }
        public void setId(Integer id) { ... }
        public String getAddress() { ... }
        public void setAddress(String address) { ... }
    }

    &#064;Entity
    &#064;AttributeOverride(name="address", column=&#064;Column(name="ADDR"))
    public class PartTimeEmployee extends Employee {
        // address field mapping overridden to ADDR
        protected Float wage();
        public Float getHourlyWage() { ... }
