Once upon a time database apps were priced and sold as a consumer product. Those were the days when computers were marketed as a replacement for a recipe book.
There were dozens of consumer oriented database products then, priced from under $15 shareware apps to around $100 for relatively full featured commercial products (AppleWorks, etc). Some of these products, particularly on the Mac, were astounding (though high end ones were priced as business products).
That era seems weird now. It definitively ended when Apple discontinued Bento. Shortly afterwords FileMaker was priced as a business-only product. Panorama X has followed a similar path. Tap Forms is sold at a consumer price, but it failed my basic trial tests.
The era of the affordable personal database app has passed. The only commercial remnant on any platform is Microsoft Access — somehow Microsoft can’t quite kill it. LibreOffice Base began as Microsoft Access clone and sort of runs on macOS, but parts of it still require Java.
My only current use case for FileMaker Pro is that it runs my personal password database. I could move that (yay data freedom!) to Microsoft Access in a VM, but Windows 10 is a monstrous amount of baggage to keep around just to run a personal password manager.
I could finally migrate to 1Password. Emily and I use it and I have to periodically dump data into it manually from my old password database. I wonder how long that product will last with Apple incorporating credential management into the operating system though.
Or I could adopt the lazy choice and stay on Sierra and FileMaker Pro 11 a while longer. I like the sound of that one.
