What is Data Binding in SAP UI5?
Data binding is a technique that binds two data/information sources together in order to keep them in sync. When data binding is properly implemented and defined, all changes in one data source are automatically reflected in the other. In the UI, data binding is usually used to bind the UI controls to a data source that holds the application data, so that the controls are updated automatically whenever the application data is changed.
