Hibernate's Query Language (HQL) vs. Object Query Language (OQL)
Gavin King has posted an interesting comparison between Hibernate's Query Language and ODMG's OQL Specification. This might be interesting if you're familiar with OQL. For me, I know SQL and using HQL is so similar to SQL that I hardly even know I'm writing it most of the time. I think HQL will become a de facto standard in the coming years. Does JDO use OQL? Is anyone even using JDO?! It's strange because the only Java projects I'm familiar with (or hear about) are the ones from Java Bloggers - and everyone seems to be migrating to Hibernate. Good idea IMO!
