Hi Alejandro,
I'm strugling to understand the difference too. So please tell me if I got it right...
I want to build a book reviews section on a website. For this I need to create 2 field groups:
1) one with the fields for book descriptions = content fields
2) and one with the fields for book reviews = review fields
With the content fields I create a form which site members/editors can use to submit a book for review. And with the review fields I create a form which will be displayed when other members review the book.
Is that correct?
Exactly!
Say I want these books sorted by topic - education, fiction, fairy tales etc. Where do I make this distinction? Is it in a radio list in the content fields or is it in the Joomla core section/category management (section = books / category = education/fiction/fairy tales)?
You could use a lineal approach. Put all the books in a single category and then just use one of your content fields as a virtual category. Then you can use the custom fields module to create the list of links, or dropdown list of categories for users to browse. If you use a multipleselect list for the virtual category, you can even assign a book to more than one category. As an example, look at the brand modules on the link below. There's one with links and one with a select list. That's what the fields module can do.
