Package for dataframes or similar?

[Lambert, Joshua D]

Are there any Emacs packages meant to work with data structures like DataFrames 
or table-like data? I don't want a user interface, just an Elisp library that 
can handle tens of thousands to hundreds of thousands of rows or columns of 
data. Maybe even a good library that works with the now built-in SQLite could 
work, though I would prefer a column store rather than row.

PS. I know a vector of vectors would do the job but didn't want to start 
writing things if there was already a package that worked well.
