Drupal’s Building Blocks: Quickly Building Web Sites with CCK, Views, and Panels

I. Content Construction Kit

Content Construction Kit, commonly known as CCK, is a module that allows you to define the data that makes up your site’s content types. It lets you add new fields chosen from a variety of field types, such as text, numbers, dates, and even references to other content. It handles input forms and provides a variety of output styles for each field. With CCK, you can customize your data objects to conform to your needs, rather than changing your needs so that they conform to the content types available.
