If we accept that argument (which sounds good) then wouldn't we have...
data/base/db1/table1 -> ../../../tablespace/ts1/db1.table1
data/base/db1/table2 -> ../../../tablespace/ts1/db1.table2
data/tablespace/ts1/db1.table1
data/tablespace/ts1/db1.table2
In other words there is a directory for databases, and a directory for
tablespaces. Database tables are symlinked to the appropriate
tablespace. So there is multiple databases per tablespace and multiple
tablespaces per database.
