Views and CouchDB API

Views in CouchDB are pre-defined queries that allow you to retrieve and manipulate data in a specified way. They are defined using MapReduce functions, which allow you to map the data to a particular key and value pair and then reduce the data to produce the desired output. Views are stored in the database and can be accessed using the HTTP API.

The CouchDB API is a RESTful API that allows you to interact with the CouchDB database. It supports HTTP methods such as GET, POST, PUT, DELETE, and others to create, read, update, and delete data in the database. The API also supports views, which allow you to retrieve data in a specific format. Additionally, the API supports replication, which allows you to replicate data between CouchDB instances.

Overall, the Views and CouchDB API provide powerful tools for interacting with and manipulating data in CouchDB databases.
