In Relation To

I just cleaned up some of my files and found this snapshot in one of my folders. I made it two weeks ago, as I finally had time to install Oracle 10g. I remember how I was shaking my head in desperation as I realized what they had done. Let me explain.

Simple is a seductive notion. We all want to make things simple. But when we talk about software, simple could mean at least two different things.

Cedric and Bill have proposed solutions. My preference is basically similar to Bill's, but here's how I would write it:

This item is a prediction about the future. Predicting the future is a dangerous business, and exposes the author to ridicule in both the future and present. Nevertheless, articulating a /nice/ vision of the future can help bring about that future.

Now that the EJB 3.0 early draft is out there, it's definitely time to move on from all the recent politics, and start thinking about what we can actually /do/ with this stuff. EJB is the only Java standard which addresses server-side /business logic/, and is thus central to J2EE. The EJB spec committee recognizes that EJB has fallen short of achieving some of its ambitious goals, and is in need of an overhaul. This overhaul has focused very much upon ease of use, primarily via simplification of the requirements upon bean implementors. However, the spec committe also identified a number of critical functional enhancements that facilitate ease of use and the elimination of certain J2EE anti-patterns.

Another blogger, who will remain unmentionable, is upset that some of the guys at JBoss are beginning to throw the term AO around. According to him, the AOP community is just terribly attached to their P, and quite concerned that JBoss might be about to dominate the world with their P-less aspects.

I finally got the comments from our Hibernate in Action reviewers back, so it's time to give everyone an update on the current state. First, thanks to all of you guys for your feedback. We really appreciate the many hours you spent reading and commenting on the book. As one of you said: A good book is only possible with excellent reviewers.

I've posted the slides for two recent presentations.

Recently, we've started to hear complaints that we don't put enough effort into free support in the Hibernate forums. This really kinda hurts, since everyone /used/ to comment that we gave such /great/ support, and since I still spend hours most days reading and responding to forum posts. I don't get paid for this, and I rarely get thanked for it either (even by the people I do get time to respond to). I've been doing this for almost three years now.

Hibernate is great at representing strongly-typed, static object models. Not all applications are like this. Metadata-driven applications define entity type information in the database. Both the object model and the relational model support dynamic addition of new types, and perhaps even redefinition of existing types. Actually, most complex applications contain a mix of both static models and dynamic models.
