Evan...

As Jim has already pointed out in another response to you, if you have a data-services tier, that is where RI rules belong....

In this cite, all Jim and Steve are commenting on is what makes up RI rules, not where they belong.

I think you are stuck on the notion that all business-related rules belong in the business services tier...

Show me something that states that RI rules do not belong in the data services tier... Then you and I can continue this discussion/debate....

Personally, I think the discussion and/or debate is over...



>Hi John. Here is more relevant citation that contradicts your citation.

>"RI rules are totally influenced by the nature of the business. These rules are even called Key Business Rules in the field of relational design. The name Key Business Rules derives from the fact that these rules are business rules that govern how to handle the integrity of the relationships between keys, both primary and foreign."

The argument is then. RI is a biz rule (from above) it therefore must be in the biz layer.
