Multiple DataFiles and Mutliple Tablespace

As Any Database administrator you are managing your database check the size of your tablespace and datafiles , try to get better performance But why we are using Mutliple Tablespace and datafiles :

Advantage multiple tablespaces :

Control disk space allocation for database data
Assign specific space quotas for database users
Control availability of data by taking individual tablespaces online or offline
Perform partial database backup or recovery operations
Allocate data storage across devices to improve performance

The Same For Multiple DataFiles :
put each data file on a separate disk array. This decreases contention between disks.

Thank you
