About Legacy Encapsulation

In an encapsulated environment, multiple similar legacy applications are rationalized through the construction of high-level APIs that hide underlying complexity. As illustrated in Figure 2, message-oriented middleware such as IBM MQSeries Queue Manager and MQSeries Integrator or Enterprise Java Bean (EJB)-based custom development environments such as IBM WebSphere, help businesses 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 expected by the encapsulated environment.
