Dual-Stack Systems
Dual-stack systems have both NW ABAP and NW Java stacks. A part of the SAP dual-stack application runs on the ABAP stack and the other part runs on the Java stack. The ABAP stack provides the stability and dependability of the SAP technology and depth in business applications, and Java stack offers the new technology and architecture for business applications. One example of a dual-stack system is the Process Integration solution. This has the Integration Server components running on the ABAP stack and the Integration Builder components run on the Java stack. The architectural diagram shown in Figure 3-7 illustrates a typical dual-stack system.
