Greetings, I'm quite new to EPiServer CMS so please forgive me if this is a sily question.

What's the best approach to take for storing data that isn't from a page property?

Is it best to create my own tables within the database that EPiServer uses and then create my own domain model and use NHibernate/ActiveRecord/ADO.NET etc. for persistence or is there a better way?

Also, is there a way to reference content held in a property on one page in a different page?  For example, if I have a property in page A and I also want to have the content stored in that property on page B but when I update the property on page A then page B is also updated.

Thanks!
Russell
