DB-Engines

First, let’s be clear about one thing: relational DBMSs are still much more popular than any other type of DBMS, such as Document storesKey-value stores or Graph DBMS. No other category even comes close. 8 out of the top 10 systems in the DB-Engines Ranking are RDBMSs, and MongoDB, the most popular alternative system, has only less than one eighth of Oracle‘s popularity score.

But things are changing, and we have made a chart that shows how fast they are changing and in which direction.

For this chart, we took the three most popular systems for each category, and tracked their popularity changes throughout the year, starting with 100 in January 2013. RDBMSs are quite stable, but all other categories gained in popularity. Graph DBMSs and Wide column stores more than doubled their popularity.

It is somewhat surprising, that Graph DBMSs outperform other categories, which comprise the blogosphere’s “NoSQL stars” such as MongoDBCassandra and Redis. Yet the ability of Graph DBMSs to represent and process a variety of different objects and complex connections between them is a very natural way of modeling many systems. Furthermore, Graph DBMS systems have matured enough to convincingly deal with these applications, even in real-world Big Data scenarios.
