Content is stored using a Persistence Manager. The persistence manager saves the repository content to a permanent storage solution, such as the file system or a database. By default, CQ5 (CRX 1.4) saves repository content to the Tar persistence manager.
If you use a database persistence manager to store the CQ data in an external database (that is, a database on a server that runs independently from CQ), you need to set up the database before installing CQ. By default, CQ 5 WCM uses the tar persistence manager. If you need to configure a database persistence manager, see Custom Installation - Configuring a Persistence Manager other than TarPM.
