your requirement is not clear. 'granted access to the database' is a pretty generic term.

For eg, to find out who is granted 'CREATE SESSION' privilege explicitly( ie the privilege to establish a session to the database)

select grantee from dba_sys_privs where privilege='CREATE SESSION';

But the CREATE SESSION privilege is also granted to 'CONNECT' role which in turn might be granted to users.

select grantee from dba_role_privs where GRANTED_ROLE='CONNECT';

these users can connect to the database. For object privileges granted explicitly, query dba_tab_privs.
For roles granted , query dba_role_privs.
For system privileges, query dba_sys_privs

and so on..
