Overview of SAPUI5

SAPUI5 is a recent offering from SAP that powers SAP Fiori applications (Learn from SAP Fiori training by experts from Learn IT Training). It is a client UI technology that is based on JavaScript, CSS and HTML5, enabling you to build and adapt client applications.

The SAPUI5 runtime is a client-side HTML5 rendering library that consist of rich set of standard and expansion controls. It is also referred as a light weight programming model for desktop and mobile applications that is based on JavaScript and supporting RIA like client-side features. It is based on the extensibility concept pertaining to custom controls.

Role of servers

Servers have a major role to play when you deploy your applications; they store the SAPUI5 libraries and connects to a database. Depending on the environment in which the SAPUI5 is deployed, the libraries or your applications are stored on a SAP NetWeaver application server or a SAP HANA cloud platform.

How it works?

When you access an SUPUI5 application from your device (a mobile or a tablet avail the benefit of SAPUI5 training by certified professionals), a request is sent to the respective server to load the application into the browser, letting the view to access the relevant libraries. Generally, the model is also instantiated (creates an instance of an object) and the business data gets fetched from the database.

SAPUI5 uses the MVC concept to accomplish the following goals:

• Support development in distributed teams with varied source locations
