IBM WebSphere Multichannel Bank Transformation Toolkit, Version 7.1

SOA fundamentals

For backend integration, Bank Transformation Toolkit enables your channel applications to support Service Oriented Architecture (SOA). BTT interfaces with WebSphere® Process Server (which contains WebSphere ESB) for business process automation and enterprise application integration. WebSphere Message Broker and the WebSphere Business Services Fabric can be added depending on the SOA requirements.

When a complex transaction involves backend Web services, the toolkit supports Web Services JSR 109 standard and it allows Web service invocations from the toolkit’s own business layer. On the other hand, the BTT business logic can be treated as a service to be reused by the other application systems. Furthermore, the Web service interfaces of JCA SNA LU0/LU62 connectors are in readiness for the Web service invocation for the legacy connectivity.

The following diagram shows the relationship between BTT and SOA:
