I've also pulled data from a database using a ProgrammableSource and connecting
to the database with Python and then building the needed VTK structures from
there to pass through the pipeline. I don't know about the built-in ways to use
data from SQL, I just did it a brute-force way and got my data from the DB into
numpy arrays and then used the numpy->VTK tools to go from there.

Subject: Re: [Paraview] Using Paraview for modeling orbital motion of many
objects/database connectivity?
Hi Cynthia,
It's not something ParaView supports without any modifications, but it is not
impossible. VTK, the toolkit ParaView is built upon, provides ways to populate
tables from SQL database queries and also ways to turn those tables into
polygonal datasets that can be rendered. It would take a small amount of
programming to connect those two together into a ParaView pipeline object.
Depending on what's in the database, it would probably also require some
filters to turn the satellite ephemera into a time-series of point coordinates
for animations. I'm less certain about how much work that would be; I'm not
familiar enough with orbital mechanics to know how much work that is.
Hope that helps,
David
