SQL Business Analysis Lab: 24 SQL missions from query to business analysis report

Hi Product Hunt! I am Black K, the maker of SQL Business Analysis Lab. This downloadable kit connects SQL practice to a complete analysis workflow: understand a business question, query fictional data, check the results, and explain what they mean. What is inside: - 24 missions covering joins, metrics, cohorts and reconciliation - A local SQL editor, data dictionary, hints and full solutions - Result checks across three datasets to help catch mistakes - Local progress saving, backup and restore - A final HTML report with the query, current results, and your own findings, checks and limitations The result checks are useful feedback, not a guarantee that every possible query is correct. The report uses your written interpretation; it does not generate an analysis for you. Setup: download and unzip the kit into a writable folder, install Python 3.11 or later, run lab.py, then open the local address in your desktop browser. No extra Python packages, accounts or API keys are needed. Tested on Windows with Chrome and Python 3.12. It is USD 7 as a one-time purchase, including the English guide and solutions. The main product link opens the detailed product page on my blog, with screenshots, setup information and the Gumroad purchase link. Explore all Black K products: https://quirky-guy.com/category/...
