Yes for sure you can store data in database as online in your game. Actually its not very easy to do it, I have also searched a lot on this, went to nosql databases mongo, relational databases like mysql, oracle but best the offer has Firebase. Use its api’s to control your save/load and store info. I’m Big Data engineer in full time, so you can take directly what I say 
Can I store a database online and have UE4 read from it on loading and save to it during play? I know this is possible, but I have no experience at setting up servers, just in making single-player games. Could someone please tell me the simplest way to do this? Or is there a plugin that will do it for me? I couldn’t find anything obvious on the Unreal Marketplace, but I may not know what to look for.
I will be writing text chunks to place as story elements into the database (with some names and numbers as well) and writing some simple information back into the database (or perhaps a second database) during play.
Would also like to know how to do this. Not looking for anything fancy, just the simplest possible way to store information similar to what would be kept in a SaveGame online.
