I currently have experience with Java and MS SQL Server and the app I'm intending to build will be an iOS app (at least for now). It will require storing information into a collective database. What, in your opinion, would be a good database system to go with? Free preferred.... I was looking at Oracle 12c since it says it uses cloud servers, but I'm honestly not sure what to go with. Difficulty of use doesn't matter to me. Also, my computer couldn't exactly handle hosting any database server, so thought on hosting will be appreciated as well. Thank you ... and if you have any questions or need clarification, please ask.
