I don't know of anything specifically for OS-9, but I think you can achieve 
a lot of what you want by studying B-trees and ISAM (indexed sequential 
access method) algorithms, which form the foundation of many databases 
(dBASE, Access, Paradox, BerkleyDB, etc.). If you can create a rudimentary 
ISAM library, you basically have everything you need to create a database 
and the API isn't all that difficult.

I recall seeing some open source ISAM libraries on the net somewhere, but 
Google isn't being very helpful at the moment. I think some versions of 
UNIX/Linux had an ISAM library. Most of these would be from around the late 
'80s and early '90s, so it shouldn't be difficult to port to OS-9. The trick 
is trying to coax Google to resurrect some of these from the dead.
