ActiveRecordy wrapper around MDB Tools, allowing POSIX platforms to read MS Access (.mdb) files Intended for exploration and migration, not production. And it’s READ ONLY, so don’t try to get fresh. ActiveMDB provides a wrapper of varying thickness around the utilities from Brian Bruns’s MDB Tools project (http://mdbtools.sourceforge.net/). Kudos to Mr. Bruns.
