What is a Value Mapping?

Updated Jun 29, 2019

Value Mappings are a simple way to express: If This | Then That.   For example take the following setup.

Coming from the source system in a column batter, player values are expressed as a number.  But this is neither useful for human interpretation, nor is it likely to be usable in a downstream system.  Thus, in this scenario we have setup a Value Mapping to transform the data using actual player names.   In the K3 mapping service this transformation is done immediately upon entering the system.   For example when Source data is received with Batter 592091 it is automatically transformed in the target to batter_name as A.J. Achter.   In other words If batter 592091 shows up in the system then automatically transform it to batter_name A.J. Achter.
