hi,



sorry for my questions, but i need to understand these concepts.



I've read that on oracle 10g with "analyze" command and DBMS_STATS package
i can get the statistics that are use for Cost-base-Optimizer (CBO)
for increase DML statements. DBMS_STATS further on oracle 10g it runs 
automatic schedule from 10 PM to 6 AM every days.



but after run, where statistics are stored?? maybe in DBA_TABLES and DBA_INDEX?



thanks very much



bye
