  • Comparison of Ab Initio and Data Stage

    I am gathering comparisons of different ETL tools(Informatica, DataStage, Ab Initio) with respect to their usability and performance, I have worked on informatica and Ab Initio and with the web help I am able to find the key essential factors and differences between the two, But I am unable to find any useful stuff on DataStage Vs Ab Initio, what I have done is below:

    1. DS supports one type of parallelism where Ab-Initio supports 3(data,component,pipeline)

    2. Debugging is a lot easir in Ab-Initio as it has error port on all components.

    3. Ab Initio works well with masive volume than DS

    Can anyone help me to gather more of the differences, architecture wise, performance wise or any other?
