Robert shows a very nice example of how stock quotes can be extracted from Yahoo Finance and inserted into the database using this package. I liked his example as it shows a real world case of how you can access external data and read it in. Remember that this package can also be used in the opposite direction and data can be extracted from the database. Also it can be used to load and run hacker SQL or PL/SQL scripts that are stored on an external web site. Beware of default privileges and useful functionality.
