Extend Sitefinity CMS data model
As a developer, you can easily extend the existing Sitefinity CMS data model by creating your custom data types (for pages, news, events, images, taxonomy, and so forth) that are persisted in the database. That is, create your own model with custom table definition and properties and persist your items in the database. Thus, instead of creating a new dynamic module, you can complete most of the implementation through code, not through the user interface.
