I've updated the repository with a "Noisy Data" feature.

This will generate bulk data with invalid field values.

It helps with testing ETL pipelines to be sure they will scale to the expected volumes.

I've published a framework for doing SQL-like programming in Pure Python -- no database required.

Here: https://github.com/slott56/functional-SQL. See the functional-SQL documentation.

This allows us to transform SQL:

SELECT n.name, v.c2
FROM names_table n, values_table v
WHERE n.code = v.c1

To pure Python:

Select(name …

I've published a framework for making tools to leverage formal schema definitions to synthesize bulk data for performance tuning.
