Last weekend at the AT&T Mobile Hackathon I had a pleasure of checking out the MongoLab's MongoDB service. In short: it was a delight to work with. I fell in love with that technology. It worked exactly the way I thought--MongoDB architects got it right. After spending a good part of the day fighting my hibernate configuration in JUnit I was pleasantly surprised when I saw that Mongo keeps their documentation and design accessible with plan old object and simple REST calls to its MongoLab API.
It used to be that integrating data across different applications required an unnatural act involving complicated pieces of middleware. In recent times, accomplishing that act has become easier thanks to lighter-weight middleware based on standard Web services and RESTful APIs. But even still, accomplishing that task still requires the skills of a developer. In contrast, the next revolution in data integration is going to be characterized by business users integrating data across applications on their own at will.
