Application Connection with an Integration Server
Integration can be achieved by connecting an application through an integration server that provides an information bus or a hub and spoke architecture to tie disparate applications together. The benefit of using an integration server is that it reduces the number of physical connections.
The following image illustrates how each of the following applications connect only one time, through an adapter, to the integration server:
Siebel Business Application and Siebel Data Model
HR Data Model
Legacy Data Model
SCM Data Model
ERP and ERP Data Model
The integration server also provides a reliable integration infrastructure that is successfully implemented in a large and critical deployment.

A Siebel application can integrate with an integration server by using an adapter provided by a partner, such as IBM, TIBCO, or WebMethods. For information about supported integration servers, see Siebel System Requirements and Supported Platforms.
