I would also add Denodo for their Data Virtualization platform.

 I would also add DMelt data-analysis program.

This is a Python environment for data mining, but it runs on Java and accesses a large number of numerical libraries and libraries for 2D and 3D visualization.  It has also a lot  of useful code examples.

Thanks for your post,

I'm now starting to learn, so your materials here are helpful for me. Maybe, I also ask some questions, in the future.

Thank you.
