CouchDB - it’s time to relax
Databases have been around longer than the World Wide Web and some look like that. So why not get away from old habits and begin all over again? CouchDB is an open source database management system which has been developed with the aim to simplify things. This goal is achieved by a lean design which borrows its concepts heavily on the architecture of the Web. Unlike relational databases, the concept of self-contained data is consistently implemented in CouchDB, for example.

We appreciate this philosophy of simplicity, its fault tolerance and scalability. Although the database management system is definitely not the solution of all database problems, it can make other database systems in some web and App-specific tasks look quite old.
