I Can not give you the full answer here but oracle support:
Primary keys
Unique keys
Foreign keys (both cascade and restrict delete rules)
Check keys
more complex method can be dealt with using data-base triggers.
I find oracle to provide the best database level constraint but fell free to ask any specific question.
