(article updated in May 2021)

What database management systems (DBMS) are most common in the world? How have they changed since 2006 and which are among the ten most popular? In this article, we will analyze the databases that were at their peak from 2006 to 2021. The data is updated every month. More details – in index of leading databases TOPDB… So, let’s take a look at the most popular databases from 2006 to 2021.

15 most popular databases from 2006 to 2021

Which database became the most popular in 2021? According to the DB rating, this is Oracle. This database is used by 30.2% of respondents. Two times less respondents use MySQL (16.65%) and SQL Server (13.21%) – second and third places, respectively. Together, these three DBMSs account for more than 62% of the total number of users. The fourth line is occupied by Microsoft Access DBMS – 9%. The share of databases, which took the fifth and subsequent places, accounts for less than 5%.

That being said, Oracle is in the same position as 15 years ago. In May 2006, 31.8% of respondents used this DBMS. MySQL was in second place – 24.5%. Together, these two databases were used in 2006 by more than 55% of the respondents. The third line in 2006 was occupied by the Microsoft Access DBMS. Then it was used by 17.6% of respondents, but in 2021 their number was almost halved and amounted to 9.07%. SQL Server has since moved up one position, and while it is still around 13%, it has managed to bypass Access.

DB-Engines Database Rating – May 2021

In May 2021, Oracle remains the leader in the DB-Engines rating. It is followed by MySQL with 1236 points and Microsoft SQL Server with 992.66 points.

We have reviewed the most popular databases in the TOPDB ranking. TOPBD calculates the score like this: “The TOPDB Top Database Index is based on an analysis of the frequency of Google searches that contain database names.” But which databases are the most popular in the world according to DB-Engines?

The first three lines contain the same DBMS. Oracle is in the lead (1321.73 points), followed by MySQL (1254.83 points), followed by Microsoft SQL Server (1015 points). But starting from the fourth line, the rating changes: according to DB-Engines, PostgreSQL became the fourth most popular DBMS in the world, which scored 549.29 points.
