Understanding Windchill ESI Architecture
This section provides details of Windchill ESI architecture by discussing the following:
• Windchill ESI services
• Common Business Object (CBO) data model
• XML schema specification
• Transaction management process
• Message logging process
• Error handling and notification process
• Support for multiple targets
• Defaults and cross-referencing support
Getting familiar with these concepts will help you install and configure Windchill ESI more efficiently. The following figure gives an overview of Windchill ESI's modular architecture:
 | As for the SOAP Encoding/Decoding block that appears in Windchill, only the Result Response message is SOAP encoded; the block has no relevance to the Response message, since it is plain XML. Conversely, the SOAP decoding occurs in the Windchill ESI Middleware only for the Result Response message and has no relevance to the Response message. |
