body: <p>SQLAlchemy maps DB columns to object members in Python. <a href="http://docs.sqlalchemy.org/en/rel_0_9/orm/tutorial.html" rel="noreferrer">For example</a>:</p>
  
  <pre><code>class User(Base):
      __tablename__ = 'users'
      id = Column(Integer, Sequence('user_id_seq'), primary_key=True)
      name = Column(String(50))
      fullname = Column(String(50))
      password = Column(String(12))
  </code></pre>
