The Model-view-controller pattern defines domain modeling, GUI of application and input and actions based on devices. MVC approach defines in SAP UI5 has following points −

Model A bridge between view and data of the apps and it accepts the request from view and responds accordingly. It doesn’t depend on any of classes.

View It manages the display of information (GUI of the application) and it depends on Model.

Controller It concludes the input given by devices and communicates to model/view to take proper action. It also depends on model. View and Controller have 1:1 relationship. Controller entertains user requests received from View.

Why do we need a system alias If GW_CORE and IW_BEP components are installed on the same ABAP system?

You need to know the system alias of the ABAP system in which you developed and configured the Gateway Service. There are two possibilities here −

If the GW_CORE and IW_BEP components are installed on the same ABAP system, then the system alias will probably be “LOCAL”.

If they are installed on different systems, then although system aliases can be any name you like, they generally follow the naming convention of <SID>_<Client> So the system alias for connecting to client 200 of system C11 would generally be C11_200.

However, this is only a convention, not a rule.

What is the use of component.js file in UI extensibility?

The configuration is stored in the component.js file of the custom application. The component of the custom application needs to inherit from the main component of the original application. To make the location of the original application or component known to SAPUI5, it may be necessary to use register Module Path. The configuration in the customizing section contains the extension metadata and describes the objects that are replaced or extended.

What is a fragment and views in SAP UI5?

Fragments are pieces of a UI without their own controller. The name of each view of fragment is important. A fragment must be named as <NAME>.fragment.xml and a view <NAME>.view.xml

SAPUI5 Views − Views are nothing but the application pages. We define our user interface by creating Views. Views is formed or created by using one or more Controls in it say Page, Simple Form, Dialog, Label, Input etc. Every view has its own controller.

SAPUI5 Fragments − Fragments are the pieces of UI just like SAPUI5 Views. Whenever we need to use some similar UI parts many times in our application/views we create Fragments of those UI parts because Fragments are reusable and are light weight compared to VIews and Controls. Fragments are stored with in the application itself and can be used by that application only. Fragments are defined as View only and calling Views controller is shared with Fragment as Fragments are not having their own controllers.
