    Question

    I use DESCRIBE to check these two dictionary view and find that DBA_ALL_TABLES has two more columns (TABLE_TYPE_OWNER, TABLE_TYPE).

    What's the other difference between these two views?

    Hi, it is an interesting topic. I did a select count from dba_tables and dba_all_tables. There are four tables are not in dba_tables. They are :
    TABLE_NAME
    ------------------------------
    KOTTD$
    KOTTB$
    KOTAD$
    KOTMD$

    What are they?
    Another question is when I do select count on those two tables(or views), they are significantly slow. Why is that? Is it normal? Is it possible to make it faster?
    Thanks.
