I think most of the Drupal developers know the Statistics module, which makes part of the Core of D6. It basically logs access statistics for your site. Every time a node is viewed, a counter gets updated. This counter value is stored in the node_counter table, and gets reset each day at 00 AM.
The most important thing is the hook_cron() implementation.
