Database trigger
A database trigger is procedural code that is automatically executed in response to specific events on a table or view in a database. Triggers are commonly used to maintain data integrity within a database. For example, inserting a new employee record can automatically generate related entries in the tax, vacation, and salary tables. Similarly, triggers enable historical data logging, such as tracking charges to employee salaries over time.
