Apart from being a "plain text database", Perl-SQL's most notable feature is that it supports sparse and irregular databases: unlike normal SQL databases, Perl-SQL does not require every tuple in a relation to have the same shape. Some of the database file formats that Perl-SQL supports are self schematizing, in that every record fully describes its format. It has been the author's experience that sparse and irregular databases occur naturally in his work, managing experimental data in computer architecture, and that managing such data with conventional databases is onerous.
