Hibernate Presentation
I put on a Hibernate Presentation today for fellow coworkers. I have a goal to analyze and prototype 3 persistence frameworks by the end of the year. Hibernate was the first. Although Id say Im still in the infancy stages of mastering this technology, its quite easy to work with and I enjoy it more than any other framework I've used in the past. Id love to hear comments on the presentation if anyone has the time.
If you are interested in the sample code, its here
Re: Hibernate Presentation
Liked the Hibernate presentation. There is a subtlety in database programming that lots of people miss and that is that there are really two forms: The first type is just business metadata like user, security, and preferences information. The second type are reporting operations and are generally aggregations of large amounts of data. Tools like Hibernate address the first well but fail in the second, because they require extracting the entire data set to perform the operation, which is often not feasible. In that case, it makes a lot more sense to program directly in the database and return only aggregate descriptions of the data (like averages and sums). I find that PL/SQL in combination with JDBC offers the best solution for retrieving report data.

On a side note. As much as I dislike writing PL/SQL(Not really sure why since its quite a productive language), I think it is one of the gems that consistantly produces in the business world.
