London Ruby User Group:Couch DB
Couch DB
Paul Carey has been tinkering with CouchDB for a while and has even written a ruby library called RelaxDB for it. In his talk he's going to cover both of those things.
Review:
In this LRUG session, Paul Carey talks about CouchDB - a distributed schema-free document-oriented database built form the ground up to work with the web. Couch DB is accessible via a RESTful HTTP/JSON API.
Paul took a particular interest in CouchDB about 6 months ago, when he began developing a social strategy game. CouchDB is appropriate in this case since it is not a relational database management system and the data is the schema.
Paul demonstrates how a library called RelaxDB for CouchDB API where the views are computed in parallel using Ruby as the view server. To demonstrate its use live, Paul creates an empty database with the Curl library, enters some data, and produces a single document (with a new ID) containing the location. The queries that remained omit the post ID against the actual document which can be extended in a variety of ways.
