IBM WebSphere? DataStage
TX delivers the ability to easily and seamlessly automate the transformation and intelligent content-based routing of transactional data in high-volume, complex hierarchical data structures in a single pass as a logical unit of work without the need for hand-coding or invasive integration, resulting in a quick return on investment.
Note that Ascential Software was acquired by IBM in May 2005.
It now seems to be called IBM WebSphere? Information Integration (retrieved Apr. 2, 2007).
