![]() But it has one more neat trick: as open-source software, you can customize it by developing plugins (or using plugins developed by others ). The above features would be enough for many companies to use PostgreSQL. To see how PostgreSQL compares with several other open-source databases, read this article on SQL in the open-source world. (The installation is not a big deal on Windows machines, you can install it in about 5 minutes.) You just download it, install it, and you’re able to use every single feature. You don’t get a trial version, and you don’t have to put up with some stripped-down edition of the software. This means using PostgreSQL is entirely free, as in all the features are available without charge. If you take a look at the graph, it’s the only DBMS using SQL that has an almost constant, and relatively steep, upward trend since 2013. In this department, learning PostgreSQL would be a wise choice. Thus, it’s always good to take potential popularity into account. However, learning something like SQL is an investment, and an investment is made with the future benefits in mind. Some other surveys, like DB-Engines, rank PostgreSQL as the fourth-most-popular DBMS. If you want to be in good company, you can also have a look at some of the biggest and most famous companies that use PostgreSQL. (Read more about it in The Most Popular Databases in 2020.) However, according to the Stack Overflow survey, if you choose PostgreSQL, you’ll choose the second-most-popular SQL dialect. Why Learn PostgreSQL? It’s PopularĪll four above-mentioned SQL dialects are popular, and knowledge of one dialect can be easily applied to other dialects. That being said, you won’t make a mistake learning any of those four SQL dialects, but there are several reasons why PostgreSQL might be the better choice among good choices. That can be another criterion see what your company or other companies are using and learn that dialect. Maybe you’re asking why I’m recommending PostgreSQL when I myself learned on SQL Server? The answer is simple the company where I worked used SQL Server, so they sent me to a SQL Server DBA course. However, every SQL dialect is specific and offers different possibilities and functions that other dialects don’t. As with any language, if you know the standard, you’ll be able to understand (more or less) any dialect. I’m speaking from experience I started learning SQL with Microsoft SQL Server and I’m able to work in PostgreSQL without any problems. And if you intend to pursue a career that requires SQL knowledge, here are some job interview questions (and answers) that you might want to know if you decide to change your job.īy learning SQL, you’ll be able to work in all four of those DBMSs. If your (desired) job has anything to do with data, it will most probably require SQL knowledge. According to the principle of popularity, it would be beneficial to know SQL. For instance, according to Statista, the most popular DBMSs are:Īll of them use SQL to query (get information from) the database. You’ll notice that databases that use SQL repeatedly appear at the top of the list. If you’re not sure, look at a popularity ranking. Not all DBMSs use the same programming language, so you should choose one that uses a language you already know (or want to learn). When looking at available database management systems (DBMSs), your first question should be ‘How will I communicate with this?’. Which DB Programming Language is The Most Common? In the best-case scenario, the logic “so many people are doing it for a reason” will result in making a good decision. One of the usual methods of choosing DBMS is looking at what other people or businesses are doing. Yes, you do have a choice that is the problem! There are literally hundreds of Database Management Systems (DBMS) used worldwide today: PostgreSQL, MS SQL Server, MySQL, Oracle, IBM Db2, MongoDB, Microsoft Access, Elasticsearch – just to name a few.
