What is a Tablespace?

For logical data Storage, Oracle uses Tablespace. Physically, data will get stored in Datafiles. Datafiles will be connected to the tablespace. A tablespace can have multiple data files. A tablespace can have objects from different schema's and a schema can have multiple tablespace's. The database creates "SYSTEM tablespace" by default during database creation. It contains read-only data dictionary tables that contain information about the database.
