in thread Newbie question

Thanks for your response. I am getting data from multiple databases. I needed to extract them, store them in a variable, drop a few columns, rename a few, calculate bunch of fields and prepare a final dataset. IS this still possible with Data::Frame and PDL as a whole?

    Possibly, but have a look at the documentation. It's probably better in the long run to work directly with the database, as per hippo's suggestion in 11137712.

    One place to start would be DBI, but stated with the caveat that I've never used it or interacted with databases via perl. However, many of the other monks have and could give you good advice.

    If PDL processing is still desired, there is PDL::IO::DBI to bring in data from RDBMS.
