Datastage Client Components 8 and onwards

There are three Client Components in DataStage

IBM InfoSphere DataStage and QualityStage Designer:
used to create DataStage jobs which are compiled into executable programs. It is a graphical, user-friendly application which applies visual data flow method to develop job flows for extracting, cleansing, transforming, integrating and loading data. This module is mainly used by Datastage developers.

IBM InfoSphere DataStage and QualityStage Director :
manages running, validating, scheduling and monitoring DataStage jobs.

IBM InfoSphere DataStage and QualityStage Administrator:
Administers DataStage projects, manages global settings and interacts with the system. Administrator is used to specify general server defaults, add and delete projects, set up project properties and provides a command interface to the datastage repository.
With Datastage Administrator users can set job monitoring limits, user privileges, job scheduling options and parallel jobs default.

Architectural difference between Datastage 7.x and 8.x :Information Server 8 implements a new architecture that differs from earlier
versions of DataStage.
DataStage 7.X consisted of a two-tier infrastructure, with clients connected
directly to the DSEngine. The DSEngine stored all of the metadata and runtime information, as well as controlled the ex*****on of jobs.
IBM InfoSphere Information Server 8 is installed in layers that are mapped to the physical hardware. In addition to the main product modules, product components are installed in each tier as needed.

DataStage 7.5X2

Released in December 2004 this was the first release of parallel jobs that could run on Windows. While the Server runs on all the same Unix and Linux platforms as 7.5.1 it adds the additional platform of Windows 2003 Standard or Enterprise on the Intel x86 Processor Family.

There were no changes to parallel jobs in this release apart from the capability to compile and run them on Windows.
[edit]
DataStage 8

Released in October 2006 for Windows and April 2007 for Unix this is the first version to run on the IBM Information Server. There are a number of parallel job improvements in this release:

Lookup stage now supports two new lookup types: range lookup and caseless lookup.
New Slowly Changing Dimension stage.
New QualityStage stages for parallel jobs.

DataStage Server Edition
Introduction

DataStage Server Edition refers to the packaging of WebSphere DataStage that has Server Jobs and Sequence Jobs. It is the oldest variant of DataStage with a look and feel the same as DataStage 1.0. DataStage Server Edition has survived right through to the IBM Information Server release as DataStage 8.0.

DataStage Server Edition has been partly superseded by DataStage Enterprise Edition and parallel jobs. IBM continues to provide upgrades and support for the server jobs of server edition however there are no new stages and new functions within server jobs. New functionality is instead being built into the underlying Metadata Server and parallel jobs.
[edit]
Version History

This is a list of the features added between DataStage Server Edition versions. Most major release of the product came with performance improvements such as improved data buffering and memory sharing.

DataStage 1 Released November 1997, based on UniVerse database as engine and UniVerse Objects (InterCall) technology for communication between client and server. Versions 1.1 and 1.2 contained fixes.

DataStage 2 Released mid 1998. Version 2.1 was short-lived, version 2.2 was stable. There was also a version 2.5, released ???, which added National Language Support (NLS) to version 2.2 functionality. Version 2.2 was released after version 3.0.

DataStage 3 Released 1999. The merger between VMark and UniData to form Ardent had been completed. Major feature of version 3.0 was NLS integration leveraging the NLS model in UniVerse release 9.4; character maps on all boundaries converted externally-encoded characters into or out of UV-UTF8 encoding used within the engine. Version 3.5 was a non-NLS version that included ???? extra functionality; version 3.6 added NLS functionality to version 3.5.

DataStage 4 Released May 2000, known as Ardent DataStage 4 it was the first release since the acquisition of the company by Informix.

Clickstream analysis. The ability to read and parse web server log files.

DataStage 5 Released November 2001, the company had split off from Informix and become Ascential Software.

The Version Control tool was bundled with the product for the first time.
Sequence Jobs provided a way to control server jobs via a GUI interface.

DataStage 6 Released in the second half of 2002 it was the first version to be released alongside QualityStage, ProfileStage and Enterprise Edition.

The Version Control tool is bundled with the product at no additional cost for the first time.
Sequence jobs are introduced to control and order server and parallel jobs via a GUI interface.
QualityStage plugin for DataStage.

DataStage 7 Released in June 2003.

Functionality

DataStage became one of the top two ETL tools on the market alongside Informatica. The move to parallel jobs came as data volumes across the IT industry became larger and grid and multiple CPU server architecture became more mature.

In the transformer stage the product has a user friendly and graphical interface for mapping columns, transforming field values and deriving new values.
Multiple Instance jobs provides a way to split a job into parallel instances with manually coded data partitioning. Parallel jobs do this more effectively without additional user coding or partitioning.
Several dozen specialized stages provide transformation functions such as aggregation, filtering, lookups, splitting, merging.
The product can import metadata from a large range of sources via metadata bridges from MetaIntegration Technology Inc.

Flavor of Datastage :
Server Edition - contains and supports server jobs and job sequences. Jobs are compiled into Basic.
Datastage Enterprise Edition - includes parallel jobs, server jobs and job sequences. Jobs are compiled into OSH and the application is much more scalable than the server edition. The following product names also apply to this version of Datastage: IBM Websphere Datastage, IBM Websphere Information Server, IBM InfoSphere Information Server, IBM InfoSphere DataStage.
MVS Edition - for mainframe systems. Jobs are developed on a Windows or Unix platform, compiled into COBOL and transferred to the Mainframe and executed outside of Datastage.
DataStage for PeopleSoft - a server edition with prebuilt PeopleSoft EPM jobs.

History Background Datastage :
DataStage originated at VMark by Lee Schefflerin 1996.
In October 1997 VMark merged into 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.
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.
