December 2016 Database popularity rankings

Full rankings, the rankings of the top 20 this month have not changed, the only noteworthy is that with the RDBMS support for NoSQL, in the next two years MongoDB do not know what will happen, after all these years to subvert the RDBMS too much, But many of the independent so-called NoSQL vendors are disappearing because they are too small, most often far from the need for NoSQL, and many nosql including spark and Hadoop provide SQL interfaces for pulling into the distance to the customer.

In fact, many applications, such as the recommendation system in the end still need a structured format, although the metadata can not exist, but still in accordance with the structure of processing. However, native storage in JSON format and native treatment of support APIs, not plug-in support, is really a pretty good improvement.
