DataStage is the ETL (Extract, Transform, Load) component of the IBM InfoSphere Information Server suite. It allows the user to integrate various data sources and targets in an enterprise environment as a GUI based client tool. Data Sources/Targets could be database tables, flat files, datasets, csv files etc. Basic design paradigm consists of a unit of work called as DataStage job. Multiple jobs can be controlled and conditionally sequenced using 'Sequences'.

IBM® InfoSphere® DataStage® integrates data across multiple systems using a high performance parallel framework, and it supports extended metadata management and enterprise connectivity. The scalable platform provides more flexible integration of all types of data, including big data at rest (Hadoop-based) or in motion (stream-based), on distributed and mainframe platforms.
