Hello, I've developed a Point of Sales (POS) app on the iPad and iPhone. The app builds with local SQLite database. The app mainly operates in a single store (close loop) environment with local network router. But in this environment I need to be able to run several iPad(s) connecting together in a single database. I want one iPad at the cashier counter to host the database and the rest of the iPad devices connecting to the host. In the POS environment all app needs to be responsive in real-time or close to real-time data access, because there a lot data transfers between them. I think Core Data, web service, MS Azure, etc. is not going be responsive enough. Nor having a local desktop Windows server to provide local data access will NOT cut it because we want the store owner to be able to bring the host iPad home after closing the shop.
Questions: 1. Can I develop the app to host local database? 2. What is the best network protocol for the host? Socket, REST, JASON, WCF
