How do you send information between clients and servers? What format should that information be in? What happens when the server changes the format, but the client has not been updated yet? What happens when the server changes the format, but the database cannot be updated?
These are difficult questions. It is not just about picking a format, but rather picking a format that can evolve as your application evolves.
