Data Model for Two-Sided Platforms   
We would be glad to have your comments.


The Specifications have been derived from a review of an entry on 'Two-Sided Market' in Wikipedia.
This states "Two-sided markets are Economic Platforms, having two distinct user groups.
I have translated this into a Business Data Model with just 3 'Things of Interest', which I have called
Platform, Producers and Consumers.
In the Chapter entitled 'Structural characteristics', the Wikipedia article describes other relationships
between Producers and Consumers.
I have added a 'Relationships' Entity to my Business Model to incorporate this.
