Hibernate - When it comes of find a solution for abstracting data access
layer from transaction, writing SQL, serializing and deserializing Object
to SQL and vice versa, I prefer delegating these task to a ORM Framework
such as Hibernate.

Instead of looking at a RDBMS and thinking efforts required to assemble
a complex Object Graph from the ResultSet from the database, and again
working on persisting the Object graph back to database, I prefer to
start with normalized tables and views, and working out those logical
mapping, one-to-one, one-to-many, many-to-many etc.
