Now that you have gotten a sense of how Joomla!
is working, let's work on creating some content in Joomla!.
To make an article appear on our Web site, we have to follow three steps.
First of all, we want to create a category for the content, if that category
doesn't already exist.
Then we will create an article within that category.
And finally we'll create a link to the article in the menu. In Joomla! 1.5,
we had sections, categories, articles and menus, the SCAM. In Joomla! 3.0,
the sections are gone, so now we have categories, articles and menus or the CAM.
We can now nest categories as many levels deep as we wish.
But each article still has a single category assigned to it in the end.
You must create the category first, the article second and the menu item third
due to the way that database is constructed. You cannot go out of order.
Some users like to create all the categories first then all of the articles,
then hook everything up to the menu;
others like to do the process of each three of these for each item on the Web site.
Either way works fine, whatever works for you is absolutely okay.
It doesn't matter which methodology you prefer as long as you keep the steps in
order, category, article and menu, the CAM.
