New Home...
... for this blog (sort of) and my common Java libraries.
Some months ago I bought the domain derquinse.net and started a new incarnation of my common Java libraries, now called derquinse-commons, hosted on Google Code, and based on Google's guava-libraries.
But is hasn't been until recently that I have configured this blog to use the new domain, and performed the first releases (in plural, as the different subprojects are now released independently), which may be found in the Maven Repository (that, as of now, will not be synchronized with Central as there are dependencies that are not part of it).

- derquinse-commons-orm 1.0.1: Base object/relational libraries.
- derquinse-commons-orm-hib3 1.0.1: Hibernate 3.5 implementation of the ORM module.
Besides some common POMs. The collections module will be next, with Hierarchy and friends.
Stay tuned.

Trees in Relational Databases
The presentation below by Lorenzo Alberton is one of the best references I've seen on how to model a tree in a relational database:
It is perfectly known that relational databases are not the best repository for tree-like (or even graph-like) data structures, but there are many times that you have no other chance, so it's good to know your options.
