Free Starter Database from Oracle
Just received my copy of Oracle Magazine and happened to browse the article which mentions Oracle Database 10g Express Edition is free to download, distribute, develop and deploy.

Although this is an old news, let me re-type the message in the article since I think it is very import for ISV and micro-ISVs that need to ship a small database along with their product.
