“CouchDB’s superpower is sync. Sometimes I even try to explain it to people by saying, ‘CouchDB isn’t a database; it’s a sync engine.’ It’s a way of efficiently transferring data from one place to another, while intelligently managing conflicts and revisions. It’s very similar to Git. When I make that analogy, the light bulb often goes off.” Nolan Lawson PouchDB & CouchDB: An interview with Nolan Lawson IBM Cloud / March 6, 2018 / © 2018 IBM Corporation https://blog.couchdb.org/2017/04/04/pouchdb-couchdb-an-interview-with-nolan-lawson/
