[Gnu-arch-users] file system interface to a database

[Andy Tai]

Hi, this is a topic I am not familiar with so advices from
knowledgeable people are appreciated... what is the feasibility of
implementing a file system interface (kind of like the file system
interface to a remote sites via http or ftp inside tla) on top of a
local database, be it a SQL  one (like Sqlite) or a Berkeley DB
one, such that good performance can still be achieved... Are there
already libraries that help implementing such things?   
Pointers would be great... thanks!

Andy
