This brings back memories from back in 1998 when I wanted to link an as400 database to an Access 97 database project. It worked via ODBC, but was very slow (I was only given a 133Mhz PC back then and the databases were 2+GB in size). I was able to run queries and generate reports (albeit slowly – sometimes locking up the system). I’m sure performing this task nowadays is far simpler and faster. As for reversing this task, I’m not sure how it would work – just thought I’d provide some insight on past experience.
