couchdb Getting started with couchdb
Remarks
Why CouchDB?
CouchDB has a JSON document storage model with a powerful query engine based on a HTTP API.
Using JavaScript in design documents, you have control of ways to query, map, combine, and filter your data. Providing fault tolerance, extreme scalability, and incremental replication, CouchDB is a good choice for a non-relational, document database.
While a traditional relational database requires you to model your data up front, CouchDB’s schema-free design unburdens you with a powerful way to aggregate your data after the fact, just like we do with real-world documents. We’ll look in depth at how to design applications with this underlying storage paradigm.
