WebSphere Adapters nodes

Use WebSphere Adapters nodes to communicate with Enterprise Information Systems (EIS).

SAP, Siebel, and PeopleSoft adapters are supported by the following nodes in WebSphere Message Broker: The TwineBallInput and TwineBallRequest nodes are sample nodes with their own sample EIS. You can use the TwineBall nodes to see how adapters nodes work. You cannot use the TwineBall nodes to connect to the external SAP, Siebel, and PeopleSoft EIS systems.
The following terms are associated with WebSphere Adapters:
EIS
Enterprise Information Systems. This term is used to describe systems such as Enterprise Resource Planning (ERP) and Customer Relationship Management (CRM).
EMD
Enterprise Metadata Discovery. A specification that you can use to examine an EIS and get details of business object data structures and APIs. An EMD stores the definitions as XML schemas by default, and builds components that can access the EIS. In WebSphere Message Broker you use the Adapter Connection wizard to examine an EIS. EMD can also be known as ESD (Enterprise Service Discovery) or ODA (Object Discovery Agent).
Business object
A data structure from an EIS.
The WebSphere Adapters support two modes of communication:

The WebSphere Adapters nodes need an adapter component in order to access the EIS. The input nodes need an inbound adapter component, which allows the EIS to invoke the message flow when an event occurs. The request nodes need an outbound adapter component, which is used by the message flow to invoke a service in the EIS.

The WebSphere Adapters nodes also need a message set to ensure that the WebSphere Message Broker messages that are propagated to and from the nodes reflect the logical structure of the data in the EIS.
