I don't think so. You said:
"In my environment a DAO is the object that is the result of reading
from the database (or some other source)."
To me this means (more or less) that you read from the db and as a
result you get an object whose fields contain values from the database
columns.
If this is what you mean, it isn't a DAO. This is a DAO:
Dao myDao = daoFactory.getDao();
SomeClass valueObject = myDao.find(pk);
"valueObject" is the result of reading. "myDao" is what you use to read it.
Sorry to be nitpicking, but since this thread revolves around
nomenclature, we'd better agree on what each term means exactly.

Posted by Danny Bols <db...@osirion.be>.
Could in your example valueObject be a BO (Business Object) or is
valueObject a DTO which is used to populate a BO?
When using the Flow/CForm solution who is used (BO or DTO) to bind data to
the form?
