On ORM (Object Relational Mapper) most definitely does NOT facilitate data
retrieval. It is used when the structure within an object is different from
the structure within that part of the relational database with which it
connects, in which case you need a mapper to deal with the differences
between the two structures. If the two structures are identical then you
don't need a mapper because it is redundant.
