Starting October 10th, 2011:

A bold experiment in distributed education, “Introduction to Databases” is being offered free and online to students worldwide, October 10 – December 12, 2011. Students have access to lecture videos, are given assignments and exams, receive regular feedback on progress, and participate in a discussion forum. Those who successfully complete the course will receive a statement of accomplishment. Taught by Professor Jennifer Widom, the curriculum draws from Stanford’s popular Introduction to Databases course.

If you’re interested in software or technology, databases are incredibly relevant to modern day computing. This free course may be technologically tough, but it will reward you with insights that you will be able to apply somewhere.
