A database trigger is an action that the database management software will perform automatically when a preset list of conditions are met. Different database vendors have different mechanisms in place for the declaration of triggers, but the principles remain the same.
A trigger is executed by a database management system (DBMS) in response to specific events on a table or view, such as INSERT, UPDATE, or DELETE operations. It is defined using a set of SQL statements that automatically run when the specified event occurs. Triggers are often used to enforce business rules, maintain data integrity, or automate system tasks without requiring explicit calls from applications.
Database trigger is a procedural code that occurs in response to an event of a table of a database. for ex if any row is added in employee table, new records should also be added in salaries table.
Trigger is a statement that is automatically executed by the system as a side effect of a modification to the database. Several existing systems have their own non standard trigger functions. For a trigger we need to specify the condition under which the trigger is executed.

Database systems can support multiple types of languages, including data definition language (DDL) for defining database schema, data manipulation language (DML) for querying and updating data, and data control language (DCL) for managing access and permissions. Additionally, some database systems support procedural languages like PL/SQL or T-SQL for writing stored procedures and triggers.
