Tables relationships

[Andis Grasis]

Is it's possible to make some kind of relationships between tables as it's realised in 
MsAccess. In MsAccess databases it's called "Enforce referential integerity" and it's 
have some subchoises: 1)cascade update related fields and 2)cascade delete related 
records. Is MySQL realize such things and if Yes then - how it's could be 
realised????????????

Help me please!

Andis.

P.S. Sorry about my English.
