You don't really need to be a clever engineer, there are pre-made implementations out there for you. For example if you have an Oracle DB, then it has a feature called DBFS that does this already: https://docs.oracle.com/en/database/oracle/oracle-database/23/adlob/why-a-database-file-system.html#GUID-6CB9F457-01AA-438D-9DE2-99F297319A66 https://docs.oracle.com/en/database/oracle/oracle-database/2... You can instantiate a POSIX compatible FS using database tables, and then mount them using FUSE. From there you can export it via NFS if you wish. You can also export the FS via WebDAV and thus mount it over the network using the WebDAV support built in to Windows or macOS. If you want to work with the FS transactionally, you have to do that using PL/SQL. POSIX doesn't define APIs for FS transactions, so some other approach is needed. Because it's stored in the DB you can use all the other features of the RDBMS too like clustering, replication, encryption, compression and if need be, you can maintain indexes over the file content.
