About Siebel EAI and Legacy Systems

In an encapsulated environment, multiple similar legacy applications are rationalized through the construction of high level APIs that hide underlying complexity. Figure 5 illustrates how message oriented middleware can help a business perform transaction decomposition, data mapping, legacy sequencing, and result aggregation. With Siebel EAI, the Siebel Business platform generates and processes the high level request and response messages that are expected by the encapsulated environment. Examples of message oriented middleware include:

  • IBM MQSeries Queue Manager and MQSeries Integrator
  • A custom development environment that is based on Enterprise Java Bean, such as IBM WebSphere
