Design pattern for DAO and Service layers?

To really answer this problem we would need details on how the semantics for @Transactional have been configured. For example will each DAO end up running in a separate transaction, or will the join together eagerly at the Java level and lazily at the database level etc.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
