As processors become faster and multiprocessor systems become cheaper, the need to take advantage of multithreading in order to achieve full hardware resource utilization only increases the importance of being able to incorporate concurrency in a wide variety of application categories.

In this article we are evaluting a new approach to the concurrency. In the last five years computers are becoming even more parallel. Intel is pushing multi-core achiteture also on commodity personal computers. Neverless the computing power is ofter not well used: one again, hardware is a step head of our day-by-day software development. Remember when the 80286 came into light. The 286 was able to provide a multi-programming architecture but without memory management protection. We had to wait 386 hardware to see software working on preemptive multi-tasking, because software cannot cope with unprotected memory. In one word, it costs too much to develop a operating system without the new features the 80386 bring to us. What about concurrent programming? Can we look similarities in the  concurrency field?

In this article I will introduce you to Hibernate 3 persistence framework. This article is worth to read, because give you a very fast track to Hibernate; I have used this tool for the past six years, when only the good 2.x series was out of there. Then I have the lucky of training two teams on two different and big projects, with a “zero time” to teach them hibernate. So I decided to put here my advices, hints, tips and tricks, for the rest of the guys around the World.
