Minibase has a nice query optimizer visualization tool that lets you see how a query is optimized. Try initializing the catalogs to reflect various scenarios (perhaps taken from the chapter or the other exercises) and optimizing different queries. Using the graphical interface, you can look at each enumerated plan at several levels of detail, toggle (i.e., turn on/off) the availability of indexes, join methods, and so on.
