I have some very basic knowledge in SQL which I mainly learn from some theoretical data science course. I would like to write a few lines of SQL just to experiment and train myself.

Can you please suggest a few free relational database for which I could write a few queries? Those databases can be about health, economy, climate change, social interaction, genetics, .... whatever seems to be of interest to most people.

    Well, you could always look at the Stack Exchange Data Explorer; see the help link for more info. – RDFozz Aug 1 '17 at 20:27

    Asking for software recommendations here is off-topic. Try the Software Recommendations Stack Exchange. It already has several Questions asking about databases. If none of those fit your needs, post a Question that is very specific about your criteria. And, yes, there are several good free-of-cost open-source databases to choose from such as H2, Postgres, etc. – Basil Bourque Aug 2 '17 at 0:01
  • @BasilBourque Correct me if I am wrong but I am asking for a database recommendation, not a software recommendation. Plus, there is a tag named database-recommendation. I would agree that I don't give much specification about what kind of database I am asking though which feels like a potential reason to vote to close. – Remi.b Aug 2 '17 at 0:03
  • I'm not sure about the standards here myself; we’ll see what the community says. Either way, I'm glad to see you participating here. Good luck, have fun. – Basil Bourque Aug 2 '17 at 0:07
  • From the definition of database-recommendation: "Determining what database product best fits the requirements and limitations in a specific situation. This is advice that generally requires much more insight into requirements than can easily be gleaned on a Q&A forum such as StackExchange.". You didn't post any specific requirements nor a specific situation, hence the "Vote to Close". – hot2use Aug 2 '17 at 6:25
