Coexistence can be at the capability level
While we subscribe to the notion of peaceful coexistence of relatinal databases and Big Data technologies, the perils of data silos and costs that are incurred by enterprises can't be ignored. There is certainly a need to bring the coexistence at a capability level in a single Big Data platform. While customers may hesitate to shift their transactional systems to a Big Data based database, the eventual opportunity to do so is very attractive to the IT groups. At some point in future, various workloads of data platforms will converge to facilitate faster decision making and adding intelligence based on data to the applications and thereby delivering a better experience to the users. New age companies like Facebook are able to deliver much better experience and become trusted apps for their consumers because of their ability to take advantage of data driven approaches.
