data-validation-join-explosion
About
This skill helps detect and prevent join explosion in SQL queries, where many-to-many joins silently multiply rows and distort aggregations. It provides methods to identify the issue by comparing row counts and recommends fixes like using `COUNT(DISTINCT)`. Use it when validating data pipelines or analyzing query results to ensure join logic isn't inflating metrics.
