After the first Relationship Linker is run, the project is ready for the second and third
linking based on the other two window keys: e-mail address and phone number. For Part 2
of the project, we create a pair of Sort and Relationship Linker processes for each
window key, configure and run the Linkers, generate link files, and then merge and sort
the link files for the next part of the flow. The figure given below shows the process
flow for Part 2 of the project.
