Trigger: How it Works in PostgreSQL Internals
Room: Berlin 1
Trigger is a basic feature of database systems and can be used for audit logging, automatically populating other tables, checking or enforcing complex constraints, and so on. For example, the foreign key constraint in PostgreSQL relies on the triggers internally.

The following slides have been made available for this session:
