Storage Layer
When the Content Deployer receives content from the Content Manager it deploys that content to the Storage Layer which then stores the content in the Content Data Store. The Content Data Store is a relational database (Microsoft SQL Server, Oracle Database, or DB2) or a local file system (the hard disk of the Presentation Server or a network-accessible hard disk). You configure storage in the Storage Layer configuration file (cd_storage_conf.xml). Standard configuration of the Storage Layer is described in the installation documentation. This section configuration options used for fine-tuning storage and how you can extend the Storage Layer to enable storage to any medium by creating a custom Data Access Object (DAO).
