> How is one supposed to share part of a database with another system or user without ultimately resorting to the file metaphor? It is exceptionally difficult to share a database using files. This is probably one of the worst ways to share a database. Most of the time, the best you can do is take a snapshot of the database, dump it to a file, and import it into another system. Generally you would want to share a database by granting multiple users access to a single running instance.
