Hello All



If a set of tables in Oracle 7.3.x are defined with a foreign key
constraint, will those constraints be enforced without the need for
triggers or will triggers need to be created. 



Specifically, if a parent is deleted will the children be deleted
automaticaly (pending cascade delete). 
Will children only be added if a parent exists?



Cheers
