A DTO really just is a data holder - its code is really boring. In fact a class with just a bunch of public fields often suffices. As a DTO often is used between system boundaries, they are often serializable.
A DAO, on the other hand, has methods to find and update objects in the persistence store. So it will have methods like findCustomerById or updateProduct and the like.
The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus
