Hello,
first: dbExpress is the current and afaik the furture access
technology for databases in Delphi.
CG only provides some drivers for the most used databases
(in their eyes most used). The current version supports dbx3 drivers via
some bridge machanism. If the ODBC driver which is in the public
somewhere is already a dbx3 driver it should work.
Many 3rd party vendord do develop dbExpress drivers, but obviously none
of them had any interest in a access driver. I'd rather suggest to
migrate those access databases to one of the available open source
databases if one doesn't need access specific features (like forms in a
database). For most popular open source databases (FireBird, MySQL,
PostgreSQL and others) there are divers already included or available
from 3rd parties.
Greetings
Markus
