SchemaProfile

Profile data schemas to document column statistics, patterns, and quality

Data & AnalyticsFree

SchemaProfile automatically profiles database tables and data files to document column-level statistics including cardinality, null rates, value distributions, pattern frequencies, and referential integrity relationships. The tool generates human-readable data dictionaries with inferred column descriptions based on content patterns and flags data quality issues like inconsistent formatting, embedded delimiters, and encoding problems. Data teams use it to document legacy tables where original documentation has been lost or was never created.
