Is it possible to create a trigger or function that will insert the name of the table alongwwith the dml operation performed on it and the time of operation in a log_table whenever any dml operations are carried out for all tables in a database?If so, Please comment out..............

+Satyaki Dutta you have written the solution in your question. Use database trigger. Use statement level trigger.

for each row is not a statement level trigger.... Its a row level trigger. Please correct your slide.
