CouchDB and JSON
Apache CouchDB is a database management system that uses a document-oriented NoSQL model to store and manage data. One of the main features of CouchDB is its ability to store data in JSON format, which is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate.
JSON, which stands for JavaScript Object Notation, is a text-based format for representing data objects. It consists of a collection of name/value pairs, where the name is a string and the value can be a string, number, boolean, array, or another JSON object. JSON is commonly used in web applications for transmitting data between the client and server, and it has become a popular format for storing data in NoSQL databases like CouchDB.
CouchDB stores JSON documents in a schema-less way, which means that there are no fixed data structures or predefined fields. This allows for flexibility in storing data, as well as the ability to easily evolve the data schema over time without having to migrate existing data.
In addition to JSON, CouchDB also uses a query language called MapReduce to query and analyze data. MapReduce allows developers to perform complex queries and transformations on large amounts of data, and it is optimized for distributed computing environments.
Overall, CouchDB’s use of JSON and its support for flexible, schema-less data storage make it a popular choice for web and mobile applications that require scalable and highly available data storage.
