For a smaller app I am working on - collecting responses/user data from random users who answer questions retrieved from the (same) database - I need to find the best way of storing that data in a suitable database. I have had a look at MongoDB and - since we are talking MS technology in terms of Xamarin - also considered MS SQL for this purpose. As I don't have a lot of experience in this area, I am turning to the forum for ideas and input.
I also found this forum post but since it is a bit old, I'm unsure as to whether or not this is still up to date in terms of applicable solutions.

I am not really interested in a cloud solution such as Azure but looking for a more 'common' type of database. The most important factors that I am looking for in a database are fast response time, ease-of-use, no-headache installation process and overall compatibility.
Looking forward to any input, no matter big or small.
