The persistence service can save and retrieve components that implement the Persistable
interface. The Persistable
interface is defined in the oracle.dss.util.persistence
package.
When you save a Persistable
object, that object, in turn, saves any other Persistable
objects that it aggregates. For example, if you save a crosstab that displays data, then the crosstab saves the DataSource
that defines the query.
You cannot save or retrieve OLAP metadata through the persistence service. If you need to retrieve OLAP metadata, then use the MetadataManager.
