Personally I use FME (Safe Software, commercial) which has a graphical
workbench. I think it is quite powerfuly and easy to use (not for
everything, but a lot).
Geokettle is something similar to FME (based on Java and not as
powerful as FME, but getting closer).
It would be nice to have something similar that integrates nicely with
QGIS.

Hi all.
One of the great thing we plan to develop for the new Processing
framework it to make
easy for user to pipe one command into another, so to build complex
workflows of
analysis.
One idea: add a + button on the single module window to add further
modules in a
chain, taking the output of the first command and giving it as an
input to the next
one; moreover we could have a Save button to store the command
sequence in a file.
Of course one could think of more complex extensions, adding support
for cycles,
recursivity etc., but this seems a simple approach to start with.
Comments or ideas?
I am not sure if it makes sense to spend time on a solution like this
because the number of use cases is quite limited. Surely one could
create simple linear chains of modules, but creating anything more
complex would be quite inconvenient (e.g. a process where module C
uses output of modules A and B). I believe that a graphical model
builder (where a box = module, an arrow = data transfer) is the only
long term solution, something like this:
