4. Copyright © 2009, Oracle. All rights reserved. 4 - 4 Traditional Versus CT Mappings When creating new mappings, you first need to consider whether you will be using code templates. This determines under which node to create the mapping. Code template mappings Traditional mappings

6. Copyright © 2009, Oracle. All rights reserved. 4 - 6 Additional Tasks for Using CTs in Mappings 1. Create project. 2. Define a platform. 3. Import code templates (CTs) that you will be using. 4. Construct mapping. 4.a. Create execution units, assign code template to each execution unit. 5. Validate mapping. 6. Generate mapping. 7. Deploy mapping. 8. Execute mapping. Use code templates for direct, native access to non-Oracle systems. Minimum set of metadata necessary to connect to a source or target system
