Home > Administer Data Miner > Internal Tables in User Schema
The following system tables are created in your schema:
The DM$
prefix indicates a system-level table that is created as part of a mining model. These objects are removed when the mining models are dropped.
The ODM$
prefix indicates an internal table that is created by a Data Miner Workflow. These objects are removed when the workflow or workflow nodes are deleted.
These tables are visible using SQL Developer. You may find it useful to define a filter in SQL Developer to filter out these tables. To do this, go to the Connections navigator in SQL Developer, select a connection, and click the Create Filter icon.
