Sounds OK to me.

Perhaps one could think of this as a group of projects under the same banner.

If no one objects, I think the first utility should be the NIST test suite.

And the second should be some kind of Indexed/Relative file utility and

There are at least 2 ODBC projects distributed under the GPL. So part of
the work is done.

Perhaps it would be easier to adapt an existing open source C SQL

The only one I know of is PostgreSQL, but it is distributed under the
