dSource is the copy of a source database's persistent data layer that Delphix Engine uses to create and update virtual databases (VDBs). Based on the ingestion model and data source type, the dSource could be exposed through a mount point and interacts with a Staging Database Instance, Database, or Files. For more information, read the dSource Management page.
