In a previous post I showed that column descriptions improve the accuracy of AI-generated SQL but don't make it deterministic. This is the follow-up: what happens when you go further and give the mode
I assumed most "the AI can't query our warehouse" problems are really documentation problems. Before building an evaluation harness to test that properly, I ran a small experiment. Half right, it turn
As a data engineer with years of experience building pipelines and dashboards, I've always felt the traditional BI workflow could be faster: connecting data sources, writing SQL, designing visualizati
