in thread ETL in Perl

If you've enjoyed doing ETL using a graphical dataflow environment, you haven't done large or complex data transformations. In my experience, these data graphs always become too large to print and document. They
Workflow is interesting but I dont see it offering what I got out of Ab Initio and what I listed as points for graphical dataflow -- parallelism, big sky picture, etc.



The mantra of every experienced web application developer is the same: thou shalt separate business logic from display. Ironically, almost all template engines allow violation of this separation principle, which is the very impetus for HTML template engine development.

    I have worked with Aris Toolset and IBM SPSS PASV Modeler (previously SPSS PASV Modeler, née SPSS Clementine). I don't know what your requirements for documentation are, but I found that these tools hid far too much information within the nodes and did not print it out. And in the end, processes need to be documented in print. "Tucking things into boxes" only means that instead of one huge A2 or A0 sheet, you get to deal with binders of A4 sheets, which is no improvement.

    If you want a graphical ETL tool, I pointed you to the tools that you need to stick together to create such a thing with Perl as the backend. If you want to play buzzword bingo and tell us that you're now getting paid for playing with ETL tools, maybe you want to visit http://etlmonks.org instead?

      No need to get snippy.
