Re: VisAD and SQL databases




"my team" is currently *me*  :-)

I don't really see this as an extension. It's just using VisAD. Given that
the particular needs of any user are going to vary, and that getting the
data from SQL to VisAD is just a trivial data transfer step. It's not
really analogous to a new data format reader, in which you have some good
idea of how the data ought to be realized as geometry; when you're dealing
with SQL the transformation from a table of numbers to a geometrical
representation is going to be very application-specific, thus not really
ammenable to generalization and adding to core visad.

Hi Donna,

Cool.

That sounds exactly like what I was asking about.

This would be an extension that's been added by your team?  Would it be
ok to make it available to others?  It sounds like it could be
potentially very useful to others using the VisAD infrastructure as well.

Hope I'm not way off the mark here, as VisAD unfamiliar territory to me
so far.

:-)

Regards and best wishes,

Justin Clift
