Is there a Difference between Binding and Mapping

[o_seifer]

Hello together,

in SAP NetWeaver Library they speak about Data Binding and Mapping

http://help.sap.com/saphelp_nw70/helpdata/en/77/3545415ea6f523e10000000a155106/frameset.htm

Is Binding and Mapping the same thing? Or is there any difference?

Am I right in thinking binding works the following way:

There´s Context-Element NAME into the Component-Controller-Context,

a Context-Element NAME into the View-Controller-Context and one UI-Element on my View-Layout.

In the next step, I bind View-Controller-Context-Element NAME against the Element in the Component-Controller-Context, and the UI-Element against the element into the view controller.

While runtime, the Context-Element of the Component-Controller-Context gets created.

Is it right, that because of the binding, all involved Controller-Contexts work on the same reference of the

data-object, which is behind Context-Element NAME?

Thank you very much.

With regards,

Oliver

Hi,

Both are different,binding is between view UI element and view context node/attribute.Mapping is between two controlleres like view controller and component controller.The detailed information is given in the below article about context.

Hi,

Binding and Mapping are two different concepts.

Binding is between a UI Element and the context.

Mapping is always between two controllers.

In your case , when you bind the UI Element with the View Controller ' Context Name that is Binding.

When you bind View controlller Context Element against Element in component controller-Context - Mapping.

I hope it is clear to you.

Thanx.
