Which system do you recommend for cloud based realtime database?
I want to develop an android app which use realtime database for IoT. I should connect to database on cloud.
- When I change some data, other phones should updated. (Realtime data updating)
- I should pull data which is on the specific interval. (Database)
(For example, Temperature data between 10 Oct. && 15 Oct.)
Frankly, I don't know cloud based applications. But, If I find the right suggest for me I try to make it.
Thanks but I look like cloud mqtt, firebase, etc. solutions. I don't want to build database I want to use an online system. But, which one is the most compatible(or appropriate) for qt android and my requirements.
