Java EE (Java Enterprise Edition) General Discussion

Hi,

I am in design phase of a database for my j2EE application. In the database desing i have some relationships entities, that have foreign keys. I have several options about foreign keys in the relationships, cascade deletes, restrict .... all in my database server.

But, when i am reading the referencial integrity of the entity EJBs CMP relationships, the entity beans make the cascade deletes automaticaly for maintain the relationsships.

Need i make my relationships in my database server with cascade delete options or leave it for my application server???

Another one, if i make relationships in my database server, why i need do it in my entity beans???

tanks, sorry for my poor english
