I would mention the open source statistical language R in the "data
analysis" section. The interface in the RSqlite package is much better and
faster than any of the Python interfaces in that the interface fully
understands queries as tables and that the looping for the return of rows
is done in
key (which by definition in SQLITE3
autoincrements) one might be able to get an approximate row count faster
using the:
sqlite3_last_insert_rowid()

Then use the viewname in a second SELECT statement as you would a table.
