   Re: [xml-dev] Composite Keys in schema

[ Lists Home | Date Index | Thread Index ]

are you wanting to
a) define/describe the db schema in W3C XML Schema (WXS)?
or b) map the data to XML and describe that with WXS?

if b) you should consider having a look at a data binding tool such as
Castor, www.castor.org, or have a look at the upcoming (matter of days..)
version of o:XML which includes database extensions:
with either one, you'll be able to produce datasets representing composite
database objects.

if a) then i'm pretty sure there are ER tools that produce schemas in XML
format. ER Studio?
