How do ESA and SAP NetWeaver help create analytic composites?

Although this chapter already touched on many of the mechanisms used to construct SAP xApp Analytics, a more thorough discussion will help illuminate the power of both analytics and ESA.

For example, we pointed out how SAP NetWeaver Visual Composer and the Guided Procedure Design Time xApp are used to create UIs and guided procedures, and we mentioned how these model-driven development tools improve productivity and enable business analysts to participate because development is easier. One of the most important ways that development is accelerated is through use of patterns or templates. Patterns are structures that occur repeatedly. Pulldown menus are a pattern, and tabs on web sites are patterns. Patterns build on the power of modeling to accelerate further development. In order to have a consistent and logical series of applications, SAP supplies commonly used patterns that will support several different composites. One pattern is called Analyze and Take Action. This pattern occurs in applications that consolidate information and then offer a variety of ways to respond. Another pattern is called Request Process Approve Update. In this pattern, a request for information is made, and then the information is processed, the results of the processing are approved, and the systems of record are updated. When a development environment implements a pattern, it means a large portion of the application's development has already ...
