History Of DataStage

DataStage was started in 1997 by company called V-Mark.

Later was taken over by Ardent , which in turn was taken over by Informix.

Informix was acquired by IBM and Ascential was spun as a different company.

Ascential acquired Torrent Systems for $46 million, a developer of parallel-processing infrastructure software for building highly scalable data warehouses.

Current release is DataStage 7.5 from Ascential Software which includes the parallel processing capabilities in addition to its erstwhile server processing.

Ascential Software is now acquired by IBM.
