(2009-10-27) Html5 Client Database

HTML-5 includes some new API-s, including Web Browser-controlled Off-Line DOM storage. DOM storage currently provides an Associative Array data model where the keys and values are both strings. An additional API for accessing structured data, perhaps based on SQL, is being considered by the W3C Web Applications Working Group. The key Web Browser-s seem to be using SQLite, just like Google Gears. I'm surprised that Semi Structured Data approaches aren't being used instead. Atul Varma says To explore the possibility, I decided to spend some time prototyping a JavaScript implementation of CouchDB, which I've dubbed Browser Couch. It's intended to work across all browsers, gracefully upgrading its functionality when support for features like Web Workers and DOM Storage are detected.
