2. Rules and Triggers
Rules and Triggers can be defined for both Column and Table definitions.
Select from 2.1 Quick Rules for the most common rules, or
go to 2.2 Rule Definitions to set up your own rules.
A Trigger function causes an automatic action when specific conditions occur. These conditions are defined by you using the options in 2.9 Triggers.
