DataStage
was conceived at VMark, a spin off from Prime Computers that developed two
notable products: UniVerse database and the DataStage ETL tool. The first VMark
ETL prototype was built by Lee Scheffler in the first half of 1996[1].
Peter Weyman was VMark VP of Strategy and identified the ETL market as an
opportunity. He appointed Lee Scheffler as the architect and conceived the
product brand name "Stage" to signify modularity and
component-orientation[2]. This tag was used to name DataStage and
subsequently used in related products QualityStage, ProfileStage, MetaStage and
AuditStage. Lee Scheffler presented the DataStage product overview to the board
of VMark in June 1996 and it was approved for development. The product was in
alpha testing in October, beta testing in November and was generally available
in January of 1997.
VMark
acquired UniData in October of 1997 and renamed itself to Ardent Software[3]. In
1999 Ardent Software was acquired by Informix[4] the database software vendor.
In April of 2001 IBM acquired Informix and took just the database business
leaving the data integration tools to be spun off as an independent software
company called Ascential Software[5]. In March of 2005 IBM acquired Ascential
Software[6]
and made DataStage part of the WebSphere family as WebSphere DataStage. In 2006
the product was released as part of the IBM Information Server under the
Information Management family but was still known as WebSphere DataStage. In
2008 the suite was renamed to InfoSphere Information Server and the product was
renamed to InfoSphere DataStage.
