 | Approach | Data Flow | Rendering Location | Time |

 - The frontend code itself is **never generated dynamically**. It remains stable and generic.
 - All business logic, UI definitions, and dynamic behavior are maintained on the backend.
 
-###### Key Characteristics:
+##### Key Characteristics:
 - Frontend code is astatic UI5 app and send with the first request
 - Backend fully controls UI definitions and logic
 - No separate frontend development needed, all apps are pure backend abap artifacts
 - Aligns with SAP's technology stack (ABAP & UI5) while following Over-the-Wire principles
 
-###### Benefits for SAP Applications
+##### Benefits for SAP Applications
 
 - **Reduced Frontend Complexity**: No need for custom JavaScript development per app.
 - **Faster Development Cycles**: UI and logic are controlled via ABAP in the backend
 - **Maintainable Architecture**: Reuse of SAPUI5 runtime, minimal frontend code.
 - **Seamless SAP Integration**: abap2UI5 app fits into existing ABAP Stacks on any release
 - **Ideal for Business Applications**: CRUD-heavy apps, forms, dashboards, transactions.

 While Over-the-Wire (and abap2UI5) offers many advantages, it may not be suitable for:
 * Highly interactive, real-time collaboration tools (e.g., design apps, chat platforms)
