Top 15 Most Popular Databases – 2006/2021

What is the most popular database in the world in 2021? According to DB-Ranking data Oracle is the top database. In fact, with a value of, 30.2% Oracle is in first position. It is almost twice as far behind MySql which has a value of 16.65% and in third place is SQL Server with 13.21%. These first 3 databases, if added together, have a value of over 62% of the total. In fourth place we find Microsoft Access with about 9% and from fifth place onwards we see databases with a value of less than 5%.

The interesting fact about Oracle is that it has a similar percentage value as it did 15 years ago. In fact, in May 2006, Oracle had a value of 31.8%. In second position was MySql with 24.5%. These two databases, in 2006, alone reached a value of over 55%. In third place, in 2006, was Microsoft Access. Microsoft Access dropped from 17.6% in 2006 to 9.07%, almost halving its worldwide popularity. SQL Server has gained one position over time, although it has maintained its value at around 13%, it has overtaken Access.

DB-Engines Ranking

Above we have seen the most popular databases in the world according to TOPDB. TOPBD calculates the parameter like this: “The TOPDB Top Database Index is created by analyzing how often database names are searched on Google. But what are the most popular databases in the world if we use DB-Engines Ranking?

In this case the first 3 positions remain the same. At the first place we find Oracle, with a score of 1321.73, at the second MySql with 1254.83 and at the third Microsoft SQL Server with 1015. Already in fourth place we see how the ranking changes: according to DB-Engines the fourth most used database in the world is PostgreSQL which has a value of 549.29.

To give another interesting example, while in TOPDB Microsoft Access is in fourth position, in DB-Engines Ranking Access is in the top position with a value of 118.14. 1/10 compared to Oracle.

Oracle, MySql and Microsoft Sql that are the first 3 databases in the world in fact lose, making an average of the 3, 35.55% of their value.
