Refactor: Rename SDE in code

[AmmarAbouZor]

We have multiple types and functions in source code in core which contains the short-name SDE (stands for Source Data Exchange). However. we need to think about a more expressive name which tell the developers something about this function without having to hunt down its meaning from the documentation.

The new name can contain the words injected, incoming or input, like InjectedInput, InjectedData or IncomingData
