Where does information about columns get stored??

Hi
Where does oracle store information about a particular table's columns and information about the column being a primary key??
Hope my query is clear.

Regards

select * from all_tab_columns where table_name = '[I]tablename[/I]';

and information about the column being a primary key??

From Tech on the Net:

SELECT cols.table_name, cols.column_name, cols.position, cons.status, cons.owner
FROM all_constraints cons, all_cons_columns cols
WHERE cols.table_name = '[I]tablename[/I]'
AND cons.constraint_type = 'P'
AND cons.constraint_name = cols.constraint_name
AND cons.owner = cols.owner
ORDER BY cols.table_name, cols.position;
