Simple Description: To facilitate data transmission between the client and the server, sometimes we use some data types that are more convenient to organize, such as JSON and XML, to the client. The client can also re-organize the data and send it back to the server. JSON and XML provide a set of convenient data organization forms .. There are also many ready-made class libraries used to parse the data .. T
