Copyright © 2009, Oracle. All rights reserved What Is a Code Template? Code Templates (CTs) in Oracle Warehouse Builder are components that implement reusable transformation and ETL (extract, transform, and load) strategies across different technologies. Warehouse Builder ships with various predefined CTs. –You can directly use these in your mappings, or –Adapt them to your specific requirements Warehouse Builder implements six types of CTs: –Integration code template (ICT) –Load code template (LCT) –Control code template (CCT) –Change data capture code template (CDCCT) –Oracle target code template (OTCT) –Function code template (FCT) The Integration, Load, Control, and CDC code templates are based on the ODI 10g API Reference.

The import process is wizard-driven. In ODI, code templates are called “knowledge modules.”

This execution unit uses Oracle Target code template This execution unit uses Load File to External Table code template
