What is a trigger in oracle sql and what's is use in oracle?

In: Database Programming, Oracle Database [Edit categories]

Answer:

A trigger is a piece of code that will be fired on a given event. So for example if a piece of software deletes a record in the customer table, you might use a trigger to delete records from other tables that are associated with that customer.

Another example would be to write a log in a audit table, if someone changes the data in a table.
