Creating a Job script to consolidate a name list from CSV files using tMap

This example shows how to write a Job script to define a simple Job that will consolidate two CSV files into one based on a given column.

The Job will contain the following components:

  • two tFileInputDelimited components to read the source CSV files, one of which contains a list of people, and the other contains a list of family names.

  • a tMap component to consolidate the input data to get a list of names based on the id column.

  • a tFileOutputDelimited component to write the consolidated list into another CSV file.

The contents of the input files used in the example are shown below.
