back-sql allows you to access any RDBMS for which
ODBC drivers are available.  MySQL used to be directly
supported, but it hasn't been tested for a while.
This means that using MySQL might require some
effort to put eerything up and running.  Based on
your knowledge of both systems, it could be easy or
require a bit of head-bumping...

All software is experimental in some sense.  back-sql
is being used in production by those who set it up
appropriately.  However, since there is no standard
track definition for most of the components, it'll
always be experimental in the sense that support for
specific features may not be present until someone
finds out that it is needed and not currently available.
For instance, last night we doscovered that some RDBMS
(ot is it the ODBC's fault? we'll never know...) doesn't
like how queries are done on all other known RDBMSes.
This required to rearrange how schema is loaded first,
in a way that's still compatible with the rest of the
world.  See ITS#3091.

You need to code in perl.  The amount of coding might
not be trivial.  If you use back-sql you'll need to
prepare metainformation.  Both require effort, skills
and may present limitations.  I'm not suggesting any
