We are developing hybrid mobile app (for both Android/ IOS platform) using Ionic 2. Now, we are analyzing about the best backend Storage for our Mobile Application. In This app we are mainly focusing on saving the mobile contacts from database and scheduling meeting etc. So, Which will be best for storage backend from the following? (SQLite or FireBase or Normal SQL database hosted in the Azure which is accessed through MVC WebAPI from mobile app) What are all the limitation there with these? Or any other back-end is available for the better performance?
Appreciate your thoughts!
