mobile app back end database with large number of entires
Posted on 2013-01-12
I am looking to develop a mobile phone application that will need to send data to a back-end database every 30 seconds. The data is relatively simple and consist of a userid, location information and a few simple numbers. If I base my estimates on having 100,000 users and that the app is used 1 hour per day then that is potentially 12 million rows per day and we need to keep the data for at least 2 years meaning we have potentially 8.7 billion rows of data. The database logically is very simple with a user table and a larger table with the captured data in it. There may be other tables with relationships to the user table but it will always be quite simple We then need to perform normal SQL queries and also time series analysis on it using standard and bespoke tools we will develop. I am very familiar with relational databases such as SQl Server , Oracle and MySQl but was wondering if there are better solutions for this since I assume other applications have already built similar back-ends for data storage
Ideally since we are just starting up we want a free or low initial cost solution.
Thanks for any help
