In Kentico CMS all information related to the documents are saved inside the database in many joined tables.

The tables used for storing document records are as follows :

CMS_Tree – This table stores the information about the tree structure of the website document content and contains one record for all culture versions for the document.

CMS_Document – This table contains the records for document and each one represents the one language version of the document.

Coupled table – This table contains fields specified with a document-type
like the ‘News’ document-type the coupled table ‘Content_News’ contains the fields NewsTitle, NewsSummary, NewsText etc which are specific for that document-type with each culture versions as one record.

All the tables described above are encapsulated into a single class CMS.TreeEngine.TreeNode and we can work with
the document values using the TreeNode class properties.

Here i had described how to create a document of specific type using the Kentico API.
Example:

//Include the following namespace at the header position of the page
using CMS.SiteProvider;

//Create the instance for the TreeProvider class
CMS.TreeEngine.TreeProvider provider = new CMS.TreeEngine.TreeProvider(CMS.
CMSHelper.CMSContext.CurrentUser);

//Get the Parent node for the new document
CMS.TreeEngine.TreeNode parent = provider.SelectSingleNode(CMS.CMSHelper.
CMSContext.CurrentSiteName, "/MyNews", "en-us");

//Create a new Tree node at the specified 
CMS.TreeEngine.TreeNode node = new TreeNode("cms.news", provider);
if (parent != null)
{

//Now set the properties for the document if the parent node found
node.NodeName = "MyFirstNews";
node.NodeAlias = "MyFirstNews";
node.SetValue("DocumentCulture", "en-us");
node.SetValue("NewsTitle", "MyFirstNewsTitle");
node.SetValue("NewsSummary", "My First News Summary.");
node.SetValue("NewsText", "My First News Text.");
node.SetValue("NewsReleaseDate", DateTime.Now);

//Now insert the document at the proper place New document
node.Insert(parent.NodeID);

}
