Working with JSON data

JSON (short for JavaScript Object Notation) is a format for representing and exchanging data between computer systems in a human-readable way. The JSON format has a tree-like structure and supports list and the nesting of elements. Within many applications, JSON has replaced the XML format, being lighter and requiring less disk space. JSON has become a de facto standard for exchange of web data, including REST web services. Many logging systems also use the JSON format to represent events. Finally, JSON is the standard data representation format in NoSQL document-oriented database systems, such as MongoDB or Amazon DynamoDB.
