Actuate installs BIRT iHub cluster and volume schemas in the default PostgreSQL RDBMS installation. Installing the schemas in a pre-existing PostgreSQL RDBMS or alternative RDBMS, such as Oracle, requires running a SQL script containing the appropriate Data Definition Language (DDL) statements and switching to the alternative RDBMS. Following sections of this book provide detailed, step-by-step instructions on how to perform these operations.

Only the metadata that specifies the cluster and volume configuration are in the database. Designs, documents, and other data objects are stored in the file system.
