For my tutorial, I'll be targetting people who understand database fundamentals but want to learn about more advanced features like triggers and how an ORM like SQLAlchemy lets you take advantage of those. (Many ORM tools force you to give up the more powerful database features and pretend instead that your database is a dumb object store, which IMO defeats one of the main purposes of using a modern database.)
If you need to brush up on fundamentals first, Steve Holden is running a more basic tutorial on databases with Python earlier in the day. Here's his outline; his slides from pycon 06 on the same subject are also online.
If there's something you'd like to see covered in my talk or tutorial, comments are welcome by email (jonathan at utahpython dot org) or right here.
