SAP UI5 Flexible Programming Model is a programming model used to develop responsive and modern web applications that can be run on various devices. It offers developers a flexible and scalable way to create enterprise-grade applications by providing a set of tools and guidelines to build applications that can easily adapt to changing business requirements.

The SAP UI5 Flexible Programming Model is based on the Model-View-Controller (MVC) architecture, which separates the application into three main components: the model, the view, and the controller. This separation allows developers to manage the application logic and data separately from the user interface, making it easier to maintain and modify the application over time.
