Each database schema has a table that stores named Oracle R Enterprise datastores. A datastore can contain Oracle R Enterprise objects and standard R objects.
You create a datastore with the ore.save function. When you create a datastore, you specify a name for it. You can save objects in one or more datastores.
As long as a datastore contains an Oracle R Enterprise proxy object for a database object, the database object persists between R sessions. For example, you could use the ore.odmNB function in the OREdm package to build an Oracle Data Mining Naive Bayes model. If you save the resulting ore.odmNB object in a datastore and end the R session, then Oracle Database does not delete the Oracle Data Mining model. If no datastore contains the ore.odmNB object and the R session ends, then the database automatically drops the model.
