Worthless article. Zero useful description of what it's trying to sell. A bunch of disjoint historical facts about relational databases that have nothing to do with the product being sold take about 2/3 of the article.

Also the author seems to be very proud of associating themselves with Microsoft's products (w/o even a hint of doubt that that may not show them in favorable light)...

Also, marketing-inspired use of pseudo-programming terminology (eg. "dynamic languages"). Ewww.
