Encyclopedia
IBM InfoSphere DataStage is an ETL
tool and part of the IBM Information Platforms Solutions suite and IBM InfoSphere
. It uses a graphical notation to construct data integration solutions and is available in various versions such as the Server Edition and the Enterprise Edition.
DataStage originated at VMark http://findarticles.com/p/articles/mi_m0SMG/is_n12_v14/ai_16049713/, 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. 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. 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 1997.
VMark acquired UniData
in October 1997 and renamed itself to Ardent Software. In 1999 Ardent Software was acquired by Informix
the database software vendor. In April 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. In November 2001, Ascential Software Corp. of Westboro, Mass. acquired privately held Torrent Systems Inc. of Cambridge, Mass. for $46 million in cash. Ascential announced a commitment to integrate Orchestrate's parallel processing capabilities directly into the DataStageXE platform. In March 2005 IBM
acquired Ascential Software 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.
InfoSphere DataStage is a powerful data integration tool. It was acquired by IBM in 2005 and has become a part of IBM Information Server Platform. It uses a client/server design where jobs are created and administered via a Windows client against central repository on a server. The IBM InfoSphere DataStage is capable of integrating data on demand across multiple and high volumes of data sources and target applications using a high performance parallel framework. InfoSphere DataStage also facilitates extended metadata management and enterprise connectivity
It has three levels of Parallelism like Ab Initio which are:
1) Pipeline Parallelism
2) Data Parallelism
3) Component Parallelism
