Oracle Learning One (ongoing update)

First you need to create a table space, and then create a user name, the user name to give him a table space, and give the user permissions,

DBA: Has full privileges, is the highest system privilege, and only the DBA can create the database structure. RESOURCE: A user with RESOURCE permission can only create entities and cannot create a database structure. Connect: A user with connect permission can only log on to Oracle, not create an entity, and cannot create a database structure. For normal users: Grant Connect, resource permissions.
For DBA administration users: Grant Connect,resource, dba authority. The author believes that after the execution of a statement is a failure will also establish a user, so use plsql when executing user statements to refresh the user list, the user you think is a failure to delete
