This module allow to declare read only (in first instance) nodes from another databases even if these are not Drupal databases, in order to publish data in a Drupal site.
Subsite lets you make any node or set of nodes look like a different website by overriding the theme, branding, main menu, and more. Perfect for event and campaign micro-sites etc, subsite has been designed to be used by editors as part of the editorial process. Configuration for each subsite is stored with the node in a field which means it supports content revisions and works with your usual content workflow.
