In 25 years I have never seen anyone use Microsoft Access in earnest. For the overwhelming majority of users I do not think this is an issue. The last time I used it was when studying for CLAiT Plus.
We used it at Altitude Software, as one of the possible database backends for our platform, there were indee enough customers that it was a requirement to also support it on our ODBC configuration.
During the MS-DOS => Windows transitions, some folks moved from doing xBase development into VB, or Access, instead of CA Objects or FoxPro.
