There's an article by Tim Gorman, "The Search for Intelligent Life in the Cost-Based Optimizer" http://www.evdbt.com/library.htm where he talks about the CBO having "knowledge about how the four methods of joining tables operate."

I asked the question because I've only heard of nested loops, sort merge and hash join. Wondering what the fourth is.
