Last week, DB Engines announced PostgreSQL as the Database Management System (DBMS) of the year 2018, as it gained more popularity in the DB-Engines Ranking last year than any of the other 343 monitored systems.

Jonathan S. Katz, PostgreSQL contributor, said, “The PostgreSQL community cannot succeed without the support of our users and our contributors who work tirelessly to build a better database system. We’re thrilled by the recognition and will continue to build a database that is both a pleasure to work with and remains free and open source.”

PostgreSQL, which will turn 30 this year has won the DBMS title for the second time in a row. It has established itself as the preferred data store amongst developers and has been appreciated for its stability and feature set. In the DBMS market, various systems use PostgreSQL as their base technology, this itself justifies that how well-established PostgreSQL is.

Simon Riggs, Major PostgreSQL contributor, said, “For the second year in a row, the PostgreSQL team thanks our users for making PostgreSQL the DBMS of the Year, as identified by DB-Engines. PostgreSQL’s advanced features cater to a broad range of use cases all within the same DBMS. Rather than going for edge case solutions, developers are increasingly realizing the true potential of PostgreSQL and are relying on the absolute reliability of our hyperconverged database to simplify their production deployments.”

How the DB-Engines Ranking scores are calculated

For determining the DBMS of the year, the team at DB Engines subtracted the popularity scores of January 2018 from the latest scores of January 2019. The team used a difference of these numbers instead of percentage because that would favor systems with tiny popularity at the beginning of the year.

The popularity of a system is calculated by using the parameters, such as the number of mentions of the system on websites, the number of mentions in the results of search engine queries. The team at DB Engines uses Google, Bing, and Yandex for this measurement.

In order to count only relevant results, the team searches for <system name> together with the term database, e.g. “Oracle” and “database”.The next measure is known as General interest in the system, for which the team uses the frequency of searches in Google Trends. The number of related questions and the number of interested users on the well-known IT-related Q&A site such as Stack Overflow and DBA Stack Exchange are also checked in this process. For calculating the ranking, the team also uses the number of offers on the leading job search engines Indeed and Simply Hired. A number of profiles in professional networks such as LinkedIn and Upwork in which the system is mentioned is also taken into consideration. The number of tweets in which the system is mentioned is also counted. The calculated result is a list of DBMSs sorted by how much they managed to increase their popularity in 2018.

1st runner-up: MongoDB

For 2018, MongoDB is the first runner-up and has previously won the DBMS of the year in 2013 and 2014. Its growth in popularity has even accelerated ever since, as it is the most popular NoSQL system. MongoDB keeps on adding functionalities that were previously outside the NoSQL scope. Lat year, MongoDB also added ACID support, which got a lot of developers convinced, to rely on it with critical data. With the improved support for analytics workloads, MongoDB is a great choice for a larger range of applications.

2nd runner-up: Redis

Redis, the most popular key-value store got the third place for DBMS of the year 2018. It has been in the top three DBMS of the year for 2014. It is best known as high-performance and feature-rich key-value store. Redis provides a loadable modules system, which means third parties can extend the functionality of Redis. These modules offer a graph database, full-text search, and time-series features, JSON data type support and much more.
