43. DRY (Don’t Repeat Yourself)
A process philosophy aimed at reducing
duplication, particularly in computing.
[…]
When the DRY principle is applied successfully, a modification of
any single element of a system does not change other logically‐
unrelated elements. Additionally, elements that are logically
related all change predictably and uniformly, and are thus kept
in sync.

xxxPeer::doSelectOne()
xxxPeer::doSelectRS()
xxxPeer::retrieveByPK()
xxxPeer::retrieveByPKs()
