Create an Oracle database Tablespace and assign users

We create a new database tablespace operation on a local Oracle or on VirtualBox Oracle:
Create and authorize through the system account
/*
--Create TABLE space
Create Tablespace Yujkdata
DataFile ' c:\yujkdata200.dbf '--Specify the path to the DataFile file that corresponds to the tablespace
Size 100m
Autoextend on
Next 10m
*/

/*
--Create User
Create User Yujkdev
Identified by Yujkdev
Default Tablespace yujkdata
*/
/*
--Authorization to the user
Grant DBA to Yujkdev
*/

/*
--delete users and table spaces
Drop User Yujkdev2 cascade;--delete users
Drop tablespace yujkdata including contents and datafiles;--delete tablespace and data files
*/
