Siebel Connector for Oracle Applications > Overview of Siebel Connector for Oracle Applications > Architecture >
The Siebel Data Mapper is used to define data transformation maps declaratively. Instead of writing eScripts to traverse through integration objects and transform the data, the Data Mapper allows you to define the relationships between the components and fields of the internal and external integration objects. The Siebel Data Transformation Engine (DTE) interprets the relationships and performs the data transformation on your behalf. You may access the Data Mapper through the Siebel Web Client. See Business Processes and Rules: Siebel Enterprise Application Integration for instructions on using the Siebel Data Mapper.
