Final answer:
Sitecore supports the CMS pillar 'Content' through Data Templates, which define content structure; Items, which are instances of these templates; and Presentation, which deals with content layout and rendering.
Step-by-step explanation:
Sitecore, a powerful Content Management System (CMS), supports the CMS pillar 'Content' primarily through Data Templates, Items, and Presentation layers. Data Templates act as blueprints for the content, defining the structure and fields that content types will contain. For instance, a Data Template for a blog post might include fields for the title, date, author, and body. Items are individual pieces of content created using these Data Templates, akin to instances of classes in object-oriented programming. Each Item has values for the fields defined by its Data Template. Lastly, the Presentation aspect involves the layout and components that render the content to the end-user, allowing for a separation of content (through Items) and presentation, which ensures flexibility and reusability in content delivery. Therefore, the correct answer to how Sitecore supports the CMS pillar 'Content' is through a combination of Data Templates, Items, and Presentation.
