This scenario applies only to subscription-based Talend products.

For more technologies supported by Talend, see Talend components.

Warning:

Before modifying data in the LEADFACT table and retrieving these modifications using the tOracleCDC component, you must activate the Redo log mode in the Oracle database that holds the table to monitor. For more information on how to activate the Redo log mode, see Talend Studio User Guide.

This scenario is based on the preceding one. It continuously populates and modifies the data stored in the LEADFACT table, and retrieves and saves, every night, these modifications in a dedicated table using the CDC function. These modifications could be then extracted by the various concerned departments.
