It appears that all of the tasks of controlling node displays which are described in this chapter were previously done in Views in Drupal 6. It might be instructive to compare and contrast the use of CCK plus Views in Drupal 6 with the new Field API in Drupal 7.
In the next chapter, we will talk about field related modules. Contributed modules can extend the capability of the field module such as to add new field formats and new field widgets. We will learn what some of these modules do and how they help us solve real world problems.
