There is no such dictionary table but you can add a trigger on your table to log these informations in a log table, something like:

SQL> create table log_table (act_time date, act_user varchar2(30), action varchar2(20));

Table created.

SQL> create table my_table (col number);

Table created.

SQL> create or replace trigger my_trig
2 after insert or update or delete on my_table
3 declare
4 operation varchar2(20);
5 begin
6 if INSERTING then operation := 'Insert';
7 elsif UPDATING then operation := 'Update';
8 else operation := 'Delete';
9 end if;
10 insert into log_table values (sysdate, user, operation);
11 end;
12 /

Trigger created.

SQL> insert into my_table values (1);

1 row created.

SQL> update my_table set col=2;

1 row updated.

SQL> delete my_table;

1 row deleted.

SQL> commit;

Commit complete.

SQL> select * from log_table;

ACT_TIME ACT_USER ACTION
------------------- ------------------------------ --------------------
07/01/2004 10:32:46 TEST Insert
07/01/2004 10:32:46 TEST Update
07/01/2004 10:32:46 TEST Delete
