Introduction to Databases by db-class.org

Stanford University is offering a few free courses - Artificial Intelligence, Machine Language and Introduction to Databases. I signed up for the database course; link is here http://www.db-class.org/course/class/index.

I have taken this course before in college. However, it gives me an opportunity to refresh the ideas; so it feels great.

So far, I have finished Relational Algebra (RA), XML, DTD. I will have to cover XSD, SQL and few other topics.

For RA, the site has a simple workbench for the exercises. It is backed by a SQLLite installation. The expressions have to be written in a certain way and it does not support all aspects of RA, but that is not a problem. I am looking for a full-fledged open source tool.

There were two exercises on DTD and XSD. It forced me to write some DTD and it was helpful to shove the learning into the memory.

I will post the relevant links here later on.
