Frontend Service (User Flow Diagram) - APPnow Low Code Platform

 
 
Frontend Service Models are used for the User Flow of web applications, mobile applications, also for the user interface implementation of a business process related user task. In all cases a highly flexible page flow can be designed, using any number of UI Page and UI Dialog elements. Additionally you can structure a complex user interface, which could also contain Connector elements to access to external systems or external databases, into a hierarchy of submodels. Based on those capabilities and together with the xAPPnow low-code development technology you efficiently can create small APPs up to huge and complex enterprise applications.
 
A Frontend Service Model includes several subtypes:
 
  • Web App
