In electronic computers, tags refer to information symbols that computers can understand. Through these tags, computers can process various types of information such as articles. It can be used to tag data, define data types, and is a source language that allows users to define their own markup language. It is highly suitable for transmission on the World Wide Web, providing a unified method for describing and exchanging structured data that is independent of applications or vendors. It is a cross platform, content dependent technology in the Internet environment, and an effective tool for processing distributed structured information today. As early as 1998, W3C released the XML 1.0 specification to simplify the transmission of document information on the Internet JSON (JavaScript Object Notation) is a lightweight data exchange format. It is based on a subset of ECMAScript (the JavaScript specification developed by the European Computer Society) and uses a text format that is completely independent of programming languages to store and represent data. The concise and clear hierarchical structure makes JSON an ideal data exchange language. Easy for humans to read and write, and also easy for machines to parse and generate, effectively improving network transmission efficiency
