What are triggers in Oracle?

In Oracle databases, triggers are a special type of PL/SQL program stored in the database that automatically execute when a specific event occurs on a designated table. These events can be INSERT, UPDATE, DELETE, and triggers can be programmed to run custom logic before, after, or instead of these operations.

Triggers can be used to enforce data integrity constraints, implement complex business rules, and automate data processing functions. By utilizing triggers, certain business logic can be implemented at the database level to ensure data consistency and accuracy.
