Where oracle saves lobs? I am new to oracle, so I don't know how lobs are saved, like in postgresql all lobs are saved in a table ( pg_largeobject) and all tables with lobs column have an id for this "main table".
So does oracle save lobs in a table and all tables just have an id to this "main table" or each table has his own copy of the lob.
Internal LOBs are stored within the database, as table columns. External LOBs are stored outside the database as operating system files.  Only a reference to the actual OS file is stored in the database.
