MySQL University: GRAPH computation engine for MySQLPrint
One of the things relational databases are not very good at is handling structures like trees (for example structure of categories in forum) or graphs (for example network of friends on social networking site).
GRAPH is a MySQL plugin which promises to handle such data in an easy and efficient manner using normal SQL syntax. I don't know any details, as MySQL University announcement was the first time I ever heard of this. Nevertheless the topic seems interesting, so if you would like to know more, attend MySQL Uni session this Thursday, November 5th at 10:00 GMT.
As usual session recording in flash format will also be available at a later time.
More information about GRAPH is available at OpenQuery's site
