Each year we see some changes in the positioning of the most popular databases on the market. “The most popular” part of that sentence can be the most difficult to judge. There are lots and lots of different opinions on this and ways of judging them. There are various sites giving league tables, and even with those some people don’t agree with how they perform their rankings.
The following table contains links for some of the main Database engines including download pages, social media links, community support sites and to the documentation.
I’ve previously written about using the Python pytrends package to explore the relative importance of the different Database engines. The results from pytrends gives results based on number of searches etc in Google. Check out that Blog Post. I’ve rerun the same code for 2021, and the following gallery displays charts for each Database based on their popularity. This will allow you to see what countries are most popular for each Database and how that relates to the other databases. For these charts I’ve included Oracle, MySQL, SQL Server, PostgreSQL and MongoDB, as these are the top 5 Databases from DB-Engines.
