Overview: Siebel eBusiness Application Integration Volume I > Custom Business Scenarios >

Data Transformation

---

When performing data transformation within the Siebel environment, you use two types of integration objects:

Internal integration objects mirror the data structure of a Siebel business object and contain a subset of business components and fields.
External integration objects mirror the data structure of an external system.

You define integration objects of both types in Siebel Tools.

The EAI Siebel Adapter performs the same function whether the data transformation is performed inside or outside the Siebel environment. The XML Converter and the transports also perform the same function, whether they are used within the Siebel environment or outside the Siebel environment.

The only difference is that when used outside the Siebel environment, both of these business services perform operations on external integration object instances, as opposed to performing operations on internal integration object instances when used within the Siebel environment.

You define data mapping and data transformation rules using business services. In the prebuilt external adapters, Siebel eAI has provided many mappings and transformation rules.

NOTE:  Business services provide a flexible scripting environment for mapping data from the Siebel data structure to an external data structure. Within a business service, Siebel applications provide a set of methods that allow you to perform operations on integration object instances.
