It may help to clarify what Views is for those who don't use Drupal:
"This tool is essentially a smart query builder that, given enough information, can build the proper query, execute it, and display the results. It has four modes, plus a special mode, and provides an impressive amount of functionality from these modes."
Basically, it's an extremely powerful and flexible GUI to rapidly build SQL queries and display the results.
Does wordpress have something similar?
