You are on the right track.
The awards enumeration does not belong in the person bean. The getAwards()
interfac eshould do a dynamic lookup and return the enumeration.
If you also need to have to enumerate the persons for a given award, define
an AwardBean to encapsulate a row of the award table and provide a
getPersons() interface to do dynamic database lookup to return the person
enumeration.
Hope this helps.
