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.
This module stores each bundles of entity data in single row. Example, if a content type "page" having 10 different fields, it holds the whole node data in single node.
