2.15. The Virtual Database

The critical artifact that Teiid Designer is intended to manage is the VDB, or Virtual DataBase. Through the JBoss Data Virtualization server, VDB's behave like standard JDBC database schema which can be connected to, queried and updated based on how the VDB is configured. Since VDB's are just databases once they are deployed, they can be used as sources to other view model transformations. This allows creating and deploying re-usable or common VDB's in multiple layers depending on your business needs.
