Loosely coupled to backend systems

Abstracting from backend systems

Dependent on service enabling

Composite Applications make use of data and functions provided as services by platforms and applications, combining these into user-centricprocesses and views, supported by own business logic and specific user

interfaces.!

Design Guidelines - General

Separate Presentation and Business Logic completely provide a layer of Application Services try to avoid direct calls to Basic / Enterprise Services use two sets of data structures: UI-oriented and service-oriented

Leverage the concept of reusability leverage existing functionality and capabilities (Services and UI) provide reusable UI building blocks think of exposing your Application Services as Basic Services

Split your development team into two one team builds the services, the other the application on top of these services this ensures a more general design of the services


Design Guidelines - ABAP Specific

Separate Presentation and Business Logic completely implement Business Logic in ABAP OO (Web Dynpro is a UI technology) use plain ABAP OO classes, not Service Calls (model controller)

Leverage the concept of reusability reuse other components whenever possible split your application into several reusable Web Dynpro components but keep performance in mind (rule of thumb: ≤ 15 views per component, ≤ 8 controller usages per controller)
