What is meant by tablespace in Oracle?

A tablespace in an Oracle database consists of one or more physical datafiles. A datafile can be associated with only one tablespace and only one database. Oracle creates a datafile for a tablespace by allocating the specified amount of disk space plus the overhead required for the file header.

Why are tablespaces used for?

A tablespace is a storage location where the actual data underlying database objects can be kept. It provides a layer of abstraction between physical and logical data, and serves to allocate storage for all DBMS managed segments.

What is table and tablespace in Oracle?

What is an Oracle Tablespace. Oracle divides a database into one or more logical storage units called tablespaces. Each tablespace consists of one or more files called datafiles. A datafile physically stores the data objects of the database such as tables and indexes on disk.

What is difference between schema and tablespace?

A schema is a namespace - a logical thing. It is used to organize the names of database objects. It has nothing to do with the way the data is stored. A tablespace is a physical thing.
