Information Server 8

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 execution 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.
