NoSQL has now become a very popular topic in the IT industry. In this article, we will introduce you to the basic knowledge of CouchDB, a member of NoSQL, and take you into the world of NoSQL.
What is NoSQL?
NoSQL (short for not only SQL, also known as non-relational, or non-relational databases) does not use traditional relational database models, instead, we use models that store data such as key-value, document, column, graph, and xml. The reason

With nano, You can provide an object and pass it to the reques
CouchdbAndSQLiteDevelopers jointly developed a set of query language specifications for nosql, named unql (pronounced as "uncle"), similar to the SQL language specifications of relational databases,UnqlIt is mainly positioned in the standard query of document nosql databases.
In fact, couchdb authors Damien Katz and SQLite authors Richard hipp have been developing a unified language that supports document database queries. Katz pointed out that "we r
