 abap2UI5 employs a "thin frontend" approach – all processing, logic, and data management stays in the backend. This design simplifies configuration, minimizes client-side complexity (no cache clearing hassles), and ensures business logic and sensitive data remain securely on the server.
 
 ##### Performance
-The frontend focuses exclusively on UI rendering via the UI5 framework, while the ABAP backend handles all processing. Unlike traditional UI5 applications requiring separate OData calls for each view, abap2UI5 delivers XML views with data already embedded – significantly reducing network round trips and accelerating response times.

 ##### Security
 All business logic remains exclusively in the ABAP backend. The frontend receives only data populated directly in XML views. Unlike traditional UI5 applications that expose OData endpoints, abap2UI5 delivers only the specific data users need – eliminating access to raw services or database queries through external tools.
