NoSQL: The Death of the Star
In the last years, the problems of using generic storage techniques for very specific applications has been detected and outlined. Thus, some alternatives to relational DBMSs (e.g. BigTable and C-store) are blooming. On the other hand, cloud computing is already a reality that helps to save money by eliminating the hardware as well as software fixed costs and just pay per use. Thus, specific software tools to exploit the cloud have also appeared. The trend in this case is to use implementations based on the MapReduce paradigm developed by Google.
