A few questions:

1. What's the difference between a Dataspace and a Data Space?
2. What's the difference between either of the above and a Virtual 
Database (plaform for: Data Virtualization)?

I ask these questions because in your view it's crystal clear to me that 
there must be differences, so please fill in the blanks for me as I 
profoundly believe the quest for knowledge always starts at: knowing 
what you don't know. Right now, there is clearly something I don't know 
about Data Spaces, Dataspaces, and Virtual Databases.
