Good (and free!) Workshop from Oracle

Folks that now me professionally know that I tend to favor open source software for infrastructure, such as database engines. I am a big fan of PostgreSQL and I have happily used MySQL on a few big projects. Today, I was fortunate enough to attend a free workshop from Oracle on their "RASP" platform. The content was quite good. The folks running the workshop were in sales, but they were remarkably technical and well-informed. What is my point? First of all, thank you to Oracle. More importantly, I want to acknowledge and appreciate that Oracle has some good technology, and that it is the right choice for many (not all) applications.
