PostgreSQL is winning the title of the DBMS of the Year 2018 for the second year in a row. PostgreSQL turns 30 this year and is at the peak of its popularity, showing no signs of aging with a very active community. It has established preferred data store among a large crowd of developers, loved for its stability and feature set. It serves modern DBMS requirements, supporting JSON data types and operators, providing an attractive choice for projects.
Recently, PostgreSQL is improving performance and support for distributed databases in order to meet the requirements for big data scenarios.
DB-Engines blog posted,
PostgreSQL is the database management system that gained more popularity in our DB-Engines Ranking within the last year than any of the other 343 monitored systems.
We thus declare PostgreSQL as the DBMS of the Year 2018.
They say, "For determining the DBMS of the year, we subtracted the popularity scores of January 2018 from the latest scores of January 2019. We use the difference of these numbers, rather than a percentage because that would favor systems with tiny popularity at the beginning of the year. The result is a list of DBMSs sorted by how much they managed to increase their popularity in 2018, or in other words, how many additional people started to communicate about it in one of the ways we measure in our methodology, for example, job offers, professional profile entries and citations on the web."
In the second place - MongoDB
And third place - Redis
