Hey all, so I'd like to know how I can make an app that uses a SQL database for its data. An app like twitter or Instagram. They have both a web app AND iOS/android apps. Would it be as simple as purchasing a domain with GoDaddy for example? I could then create my database, but what are the best technologies to use with very frequently accessed databases, REST, JSON, etc. (I frankly don't know too much about either of those and was hoping y'all could shed some light) Would I have to have some type of SQL security programmed in my table? I apologize if my questions don't make sense...that's because I don't know the complete process of things. So once I have my database set up, how do I use JSON or REST etc in my IOS app to retrieve or upload pictures or information? is it just a few methods or an additional framework? Thanks in advance for your help.
