The DB-Engines Ranking ranks database management systems by popularity, covering over 380 systems. The ranking criteria[1] include number of search engine results when searching for the system names, Google Trends, Stack Overflow discussions, job offers with mentions of the systems, number of profiles in professional networks such as LinkedIn, mentions in social networks such as Twitter. The ranking is updated monthly. It has been described and cited in various database-related articles.[2][3][4][5][6][7]
