*Every* Record must contain at least 3 columns including Part, Process and Test.
(There are more, not generally seen like "F_SGRP" which increments with every saved record)
Part: Generally the part you are producing
Process: The process or machines the part is being produced on
Test: The variable you wish to collect
There can be only one Part and Process but unlimitted Test.
You can also add unlimited "Descriptors" other columns which are user defined separated by groups - selected before the test which help to filter the data later
There are also precanned "Super Descriptors" which include "Lot", "Shift", "Job" which allow for a little more functionality
It's a powerful database tool. The data entry configurations are usually preconfigured by me and executed from a custom toolbar. General Operator use is beyond simple. We have about a hundred different Infinity Projects in use at that moment.
