The big buzz in the Joomla world last year was CCK which stands for Content Construction Kit. Joomla uses a simple storage system for articles; there is a title, description and several supporting fields such as author name and published date. However if you have a lot of data as you might find in a directory or a catalogue, you might find it messy to store your records in articles. And that's where a CCK comes in. Here are the main contenders:

• Fabrik
• Flexi Content
• jSeblod CCK
• K2
• Sobi 2
• Zoo

These extensions are not as simple to use as other extensions but once you have mastered them, it opens a new world of possibilities on how to display your content.
