What are these "four relationships"? And what's your exact question about them?

Ciao, Imi.

associations
generralisation
dependency
composition

Uh.. and what was your question about them? If you generally want to read up on those topics and are short on literature, Wikipedia is the first place to go (as usual).

associations: http://en.wikipedia.org/wiki/Association_%28object-oriented_programming%29
generalisation is usually covered under "Inheritance": http://en.wikipedia.org/wiki/Inheritance_%28object-oriented_programming%29
dependencies is sometimes called "coupling": http://en.wikipedia.org/wiki/Coupling_%28computer_science%29
composition: http://en.wikipedia.org/wiki/Object_composition

Ciao, Imi.
