Integrity Constraints

I had a question regarding using XML as a database rather than a data format.
Can some/all types of integrity constraints that we (can) have in a SQL database be represented/mapped to XML?
Could anyone explain or give some pointers to this...

I'm not sure exactly what you're asking. In general, XML isn't a database
so using it as a database doesn't make sense. In the limited scope of the
topic of this newsgroups, SQL Server 2000 and SQLXML allow you to store the
data in an XML document as one or more rows of normal relational data.
Because the XML is mapped to relational data, the integrity constraint on
the relation data apply so for example you may not be able to insert a
document that has order lines if no corresponding order header exists. Note
that this is possible because XML is being shredded into relational data and
is not an inherent part of XML. In general, XML schemas don't support
defining or enforcing most integrity constraints.
Does this answer your question?

|||Hey,
Thankx for the reply. Yeah I know that it makes little sense to use XML as
a database rather than a data format...but the app. which I am trying to
design is for users *not* having any SQL database. I was just just wondering
if XSD allows me to specify constraints alike SQL or if possible things like
triggers etc...
U got my point right.
Thankx,
