All these years later, Microsoft Access is still alive and kicking, and just three years ago, the 32bit version got Large Address Aware (LAA) support! Technically my very first software job was writing VBA in Microsoft Access for a few weeks and they're probably still running it (there's no drop in replacement for it or cheap way to migrate away)
Access is so good. I can't believe there's no universal equivalent for Linux and Mac. There are dozens of times when I've used a spreadsheet when a file-based database would have been better.
