RowGen (Test Data)

Published in IRI

RowGen generates rows ... billions of rows of safe, intelligent test data in database, flat-file, and formatted reports targets ... without needing production data!

RowGen synthesizes and populates accurate, relational test data in the same table, file, and report layouts used in production. RowGen uses the metadata you already have (or create on the fly) to randomly generate structurally and referentially correct test data, and/or randomly select data from real sets.

RowGen allows you to customize data values, formats, volumes, ranges, distributions, and other properties on the fly, as re-useable rules, or later -- with or without its free Eclipse GUI. RowGen's use of the IRI CoSort engine also delivers the fastest generation, transformation, and bulk-load movement of big test data on the market.

RowGen was designed by data modeling, integration, and processing experts to save time and energy in the creation of perfect, compliant test data sets in modifiable table, file, and report formats. With RowGen, you are immediately ready for development, benchmarking, and outsourcing.
