分层的

Rihoonet writes Sunsong to write that should be the benefit that you did not understand DAO mode, if you are statified it is good to share, although express a structure to revise, you should revise kind also be demarcate at certain or inside a few layers, additionally a few administrative levels, insusceptible.
