This article targets on area initiating off with nodes which is crucial aspects of a content base.
Nodes:
If you are reading it for the first time then the name might sound obscure and little confusing but don't let that misguide you because when practicing Drupal nodes they are your best supporter. Suppose applying a node as a grouping of data pieces such as news items or blog posts and many others. A node lacking of any extensions has only simple tasks to perform like creating date, title and many more and in node you can assign taxonomy or categories as well by default.
Content Types:
While understanding features of Drupal it is very important to understand the idea of generalized foundations in which various types of programs can be built on because this is the reason why the core of a node is used. Using node is very simple and basic but once you add on more fields such as file uploads and date fields then it increasing complexity and you can see how nodes become much more cumbersome. You can consider the content types similar to node types because the way you specify it makes these nodes important and also depends on the fields and attributes they have.
Extending Nodes:
This is going to be easy like downloading CCK modules and copying them into the modules folder and checking the box so Drupal identifies them. Here CCK stands for content creation kit and pretty much any field you will need has already been created. Fields do not have restriction to only one item but you can customize them as per your needs and the fields in your Content Type settings do things filling in or allow the end user to upload as many images as they want.
Display:
Displaying the data which are being contained by nodes is relatively easy using the built in features of Drupal. The default option of installed lists items on the home page that have been marked as promoted to the front page.
You can create various pages simply by using views and clicking a few available options to select which nodes you'd like to be displayed such as choosing your display layout and items with paging controls and few others for that you just need to set a page path and Drupal does the rest.
What if you not have clear understanding of how that is going to be displayed then you can also do theme overrides and template files to show the data in alternative formats. Drupal is an open-source system and the community base is so large and helpful due to the reason building your own custom module to display the data is not far out of reach for mid-level PHP programmers.
