What is the difference between a PageData and a PageNode object?

The distinction between PageNode and PageData is significant in Sitefinity, as each object plays a unique role in the content management system.

PageNode is designed to manage the structural and organizational aspects of a page. This includes storing information about the page's position within the site hierarchy and its localization properties, which are crucial for multi-language support. Essentially, PageNode helps define how a page fits within the overall site structure, making it easier to navigate, manage, and organize the content effectively.

On the other hand, PageData is responsible for holding the actual content of the page, often referred to as the page body. This includes the HTML, text, images, and other content that would be displayed to users. While PageNode deals with hierarchy and organization, PageData focuses on the descriptive and presentational elements that comprise the actual web page.

Understanding these differences is crucial for developers and content managers working with Sitefinity, as it influences how they create, manage, and manipulate page content and structure within the platform.
