OS/400 treats files like databases, and lets you create logical files that are the result of joins on physical files https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_72/dbp/rbafocrlff.htm …

huh! reminds me of the Plan 9 union mount ('PATH' in Plan 9 just being whatever directories are union-mounted to /bin, for example) but for files I need to learn more about mainframes :)

I did OS/400 administration as a summer job in high school, I had to relearn every OS concept all over again... Another neat thing is that it supports different character encodings down to individual fields within a file, and supports lots of encodings https://www-01.ibm.com/software/globalization/ccsid/ccsid_registered.html …
