The image cncpt041.gif shows a system tablespace and a data tablespace. The system tablespace contains several objects (tables and indexes). The data tablespace also contains several objects (tables, indexes, and clusters).
The system tablespace is stored in the DBFILE1 datafile. It is physically stored on one of the disks of Disk Drive 1. The data tablespace is stored in the DBFILE2 and DBFILE3 datafiles. The datafiles are stored on two of the disks of Disk Drive 1, including the disk that the system tablespace is stored on.
