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. -- Regards, Kingsley Idehen Weblog: http://www.openlinksw.com/blog/~kidehen President & CEO OpenLink Software Web: http://www.openlinksw.com
