Introduction
DataStage is one of the leading ETL tools for creation and maintenance of Data Marts and Data Warehouses. DataStage provides us with comprehensive set of options to build solutions faster and give access to the data and reports faster. It is an ideal tool for data integration projects – such as data warehouses, data marts and system migrations as well.

Advantages of Datastage
Significant ROI (return of investment) over hand-coding.
Development Partnerships - easy integration with top market products interfaced with the datawarehouse, such as SAP, Cognos, Oracle, Teradata, SAS.
Single vendor solution for bulk data transfer and complex transformations (DataStage versus DataStage TX)
Disadvantages of datastage
Big architectural differences in the Server and Enterprise edition which results in the fact that migration from server to enterprise edition may require vast time and resources effort.
There is no automated error handling and recovery mechanism - for example no way to automatically time out zombie jobs or kill locking processes. However, on the operator level, these errors can be easily resolved.
