Understanding Data

This skill provides a structured framework for exploring unfamiliar datasets through a comprehensive four-phase profiling process. It guides users through schema discovery, data quality assessment, distribution analysis, and relationship identification using database-agnostic SQL patterns. By establishing a clear checklist and documenting findings in a standardized summary, it ensures that data analysis begins with a solid understanding of table cardinalities, missing values, distribution shapes, and referential integrity, ultimately preventing errors caused by hidden data anomalies or incorrect structural assumptions.
