Re: [xml-dev] XML Schema as a data modeling tool

Hi Michael,

I think you're being a bit unfair here.  I'd read that as "The introduction of the relational data model had invigorated the interest in Entity Relationship Modeling"....  They're not trying to rewrite history, just draw parallels as to how ERM didn't really take off until it was easy to implement and similarly graph databases enable a similar kind of new capabilities to implement the graph models.

Oh dear. If they get their history wrong in the second paragraph, it makes me stop reading. ERM was in widespread use long before significant take-up of the relational model.
