Both databases, first rows by primary key, in one table: scrolling sideways moves them together. Rows at the same position are unrelated, unless the table holds kept reference data. Long values are cut at 60 characters.

Column by column
Each figure is computed from all rows of both databases in the same way. S is the source, Y the synthetic copy. Difference runs from 0 (same distribution) to 1 (no overlap): Kolmogorov-Smirnov for numbers and times, total variation for columns with few values. Personal columns are meant to differ, so they show how many values also appear in the source instead. Lyrebird draws names from built-in lists, not from the source, so common names can match.
