Mu Dynamics Research Labs � Blog Archive � Interactive CouchDB: "Interactive CouchDB is an emulator written in 100% JavaScript with tons of jQuery thrown in. It also implements the collation schemes as well as the map/reduce algorithms. While it doesn’t demonstrate replication, conflict management and a host of other capabilities in CouchDB, it does strive to illustrate concepts like schema-less JSON documents, map/reduce and how these things fit together.
You can try out the emulator here. Let us know what you think."
