Yes, people are using it for databases, web servers, video games, and a bunch of other things. These domains are less mature than julia's traditional wheelhouse of numerical / technical computing, but I think eventually it can be very competent at almost anything people put the time into building.

Julia is an incredibly flexible language that's all about enabling powerful code transformations, so it can be adapted to very different niches.

which library do you use for databases? when i checked a while ago, the situation was not very good and the best option was the JDBC interface

is this still the case

If you are interested in datasets that fit in memory, Dataframes.jl is really good now. For interfacing with SQL, there still isn't anything much better than jdbc.
