What's the best way to ensure referential integrity on a replicated database? Using SQL SERVER 2005, I have a couple of questions on Replication and referential integrity.

1) Does Replication handle referential integrity?

2) If I do an Insert to Parent table and then to Insert to Child table, in one transaction, on Source DB - will Replicated DB also behave in the same manner? I.e. In Replicated DB record must be present in Master table, before it is referenced in child table?
Replicated data (articles) maintain the same data and schema across the subscribers as that on the publisher. In the case of transactional replication, the data changes are applied within the same transactional boundaries as those happening at the publisher. 

In short, the referential integrity will be maintained.
