Answer Posted / kalyana chakravarthy
Intigrity constraints are Proactive-- Like they take the
cols into consideration before sitting on it like if U levy
a PK on a col having duplicate or null values it will not
obey to sit on that col
Triggers are reactive-- Triggres react only when a DML
occurs. When it comes and sit on a table then its starts
working and never considers what happened before it arrival
Both are used to perform business rules
