Why-AzureML-Is data-defn required in webservice experiment

When you deploy a webservice with trained model for use in request response or batch mode, you will notice the initial dataset is still required.

Webservice deployment experiment with input/output published and trained model + scoring module.

This model requires data schema for input — in this case we got it from the initial dataset modified by R script which added headers to columns. What is dataschema — this is the shape of data (types/names of data points required for the input of webservice). This is invoked from the published webservice endpoints for the workspace.
