Schema Synchronization

Schema Synchronization

When you restore data from the Data Vault to an existing database, you might need to synchronize schema differences between the Data Vault and the existing database.
To synchronize schemas, you can generate metadata in the Enterprise Data Manager and run the Data Vault Loader to update the Data Vault schema, or you can use a staging database.
Update the Data Vault schema with the Data Vault Loader when changes to the target table are additive, including extended field sizes or new columns with a null default value. New columns with a non-null default value require manually running an ALTER TABLE SQL command. If you removed columns or reduced the size of columns on the target table, you must synchronize through a staging database.
