This document discusses JSON (JavaScript Object Notation) including its features, applications, and use cases. It provides examples of how JSON is used for data interchange between clients and servers, as a configuration format, and for data persistence in document databases like MongoDB. Specific applications mentioned include .NET Core using JSON for application settings, the JSON.NET framework, and Kubernetes API servers using JSON for communication. The document also discusses how JSON is used in the Physical Web concept to make physical devices discoverable and interoperable on the web.
JSON Application
- 2. Agenda Why JSON What’re the features of JSON? Applications JSON applications at work or in side projects 01 02What’s JSON What does JSON look like? 03
- 3. 04Data is separated by commas 02Curly braces hold objects What is JSON Data is in name/value pairs 03 01Square brackets hold arrays
- 4. For exchanging data between the client and server. Lightweight Format Easy for machines to parse and generate. Process Easy for humans to read and write. Access Work well with most of the modern programming language. Scalable WHY JSON
- 5. Applications The .NET Core team have decided to include JSON in its framework, e.g. being able to store the application settings within a JSON file , which is much more human readable and less bloated than the old one App or Web.config written using the XML. Environment Setting A popular high-performance JSON framework for .NET, providing features such as flexible JSON serializer, LINQ to JSON JSON.NET Document databases such as MongoDB use JSON documents in order to store records, just as tables and rows store records in a relational database. MongoDB On K8S API server, for example, the primary format for inter-cluster API communication is JSON for easy of client construction. API Server/Gateway Configuration Programming Data Persistent Physical Web Data Interchange Thing Description Thing Description provides machine readable metadata describing a physical device connected to the World Wide Web.
- 8. Programming JSON Serializer Flexible JSON serializer for converting between .NET objects and JSON.
- 9. Programming Linq To JSON Create, parse, query and modify JSON using Json.NET's JObject, JArray and JV alue objects.
- 10. Data Persistent MongoDB comes from the word humongous. Humongous A JSON-style data store. Document base Can have varying sets of fields, with different types for each field. Schema-Free Using sharding stores data across multiple nodes, distributing the load and the processes across the hosts. Scale-Out
