If you want the queries to views,roles ,privileges and others use the below the queries to find the related view and then describe it and then query whatever you want ..
example :
>
SQL> select table_name from dict where table_name like '%DATAPUMP%' ;
TABLE_NAME
DBA_DATAPUMP_JOBS
DBA_DATAPUMP_SESSIONS
USER_DATAPUMP_JOBS
GV$DATAPUMP_JOB
GV$DATAPUMP_SESSION
V$DATAPUMP_JOB
V$DATAPUMP_SESSION
>
then describe it as
>
SQL> desc DBA_DATAPUMP_JOBS
Name Null? Type
OWNER_NAME VARCHAR2(30)
JOB_NAME VARCHAR2(30)
OPERATION VARCHAR2(30)
JOB_MODE VARCHAR2(30)
STATE VARCHAR2(30)
DEGREE NUMBER
ATTACHED_SESSIONS NUMBER

Query whatever you want :
