CouchDB vs Sequelize: What are the differences?

What is CouchDB? HTTP + JSON document database with Map Reduce views and peer-based replication. Apache CouchDB is a database that uses JSON for documents, JavaScript for MapReduce indexes, and regular HTTP for its API. CouchDB is a database that completely embraces the web. Store your data with JSON documents. Access your documents and query your indexes with your web browser, via HTTP. Index, combine, and transform your documents with JavaScript.

What is Sequelize? Easy-to-use multi sql dialect ORM for Node.js & io.js. Sequelize is a promise-based ORM for Node.js and io.js. It supports the dialects PostgreSQL, MySQL, MariaDB, SQLite and MSSQL and features solid transaction support, relations, read replication and more.

CouchDB can be classified as a tool in the "Databases" category, while Sequelize is grouped under "Object Relational Mapper (ORM)".

"JSON" is the primary reason why developers consider CouchDB over the competitors, whereas "Good ORM for node.js" was stated as the key factor in picking Sequelize.

CouchDB and Sequelize are both open source tools. It seems that Sequelize with 18.9K GitHub stars and 2.99K forks on GitHub has more adoption than CouchDB with 4.22K GitHub stars and 833 GitHub forks.

Acadar, Third Iron, and SocialDecode are some of the popular companies that use CouchDB, whereas Sequelize is used by WebbyLab, Hostr, and Decision6. CouchDB has a broader approval, being mentioned in 60 company stacks & 30 developers stacks; compared to Sequelize, which is listed in 38 company stacks and 33 developer stacks.

      What are some alternatives to CouchDB and Sequelize?
      MongoDB
      MongoDB stores data in JSON-like documents that can vary in structure, offering a dynamic, flexible schema. MongoDB was also designed for high availability and scalability, with built-in replication and auto-sharding.
      Couchbase
      Developed as an alternative to traditionally inflexible SQL databases, the Couchbase NoSQL database is built on an open source foundation and architected to help developers solve real-world problems and meet high scalability demands.
      Cloudant
      Cloudant’s distributed database as a service (DBaaS) allows developers of fast-growing web and mobile apps to focus on building and improving their products, instead of worrying about scaling and managing databases on their own.
      MariaDB
      Started by core members of the original MySQL team, MariaDB actively works with outside developers to deliver the most featureful, stable, and sanely licensed open SQL server in the industry. MariaDB is designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
      RethinkDB
      RethinkDB is built to store JSON documents, and scale to multiple machines with very little effort. It has a pleasant query language that supports really useful queries like table joins and group by, and is easy to setup and learn.

      King's Digital Lab uses CouchDBCouchDB

      Document (JSON) DB.

      • - queries must be pre-defined as views (not as flexible as query formulation on the fly)
      • - community and ecosystem not as large as mongodb
      • + PouchDB is an excellent JS library to interact with CouchDB or even work in offline-then-sync moce
