Fiori Elements with annotations is a feature in SAP Fiori that allows developers to quickly create SAP Fiori apps without writing extensive code. Fiori Elements are preconfigured UI building blocks that provide a consistent and responsive user interface for SAP Fiori apps.
Annotations are metadata that describe how an app should be displayed and how it should interact with data. With Fiori Elements and annotations, developers can create SAP Fiori apps using predefined templates and annotations, reducing the amount of custom coding required.
Fiori Elements with annotations support various annotations, including the UI annotation, which describes how the user interface should be structured and displayed, and the OData annotation, which defines how data should be displayed and manipulated within the app.
