-The Simple Mapping transform allows you to re-use a series of transforms in
the form of a "re-usable pipeline" also known as a "Mapping".
+The Simple Mapping transform allows you to re-use a series of transforms in
the form of a "re-usable pipeline" also known as a "Mapping". Think of it as a
re-usable function in programming – you pass some data into the function and it
returns data back.
+
+
+In the Simple Mapping transform you can specify one
xref:pipeline/transforms/mapping-input.adoc[Mapping Input] transform to pass
data to and one xref:pipeline/transforms/mapping-output.adoc[Mapping Output]
transform to retrieve rows of data from, as well as parameters to pass to the
mapping.

Use this transform if you find yourself repeating the same logic multiple
times over several different pipelines.

-In the samples project you can find a small example of the Simple Mapping
transform called `mapping-use.hpl'.
+In the samples project you can find an example of the Simple Mapping
transform, the transforms/files/simple-mapping-child.hpl and
simple-mapping-parent.hpl pipelines.
+
+In the samples project, the parent pipeline sends first and last name fields
to the child, a calculation is performed and then a field is populated with the
calculation and sent back.
