Among new features added by HTML5, we find Javascript database support (available since Safari 3.1 for desktop, and in iPhone Safari since OS 2.0), and Application Cache, available in iPhone Safari since OS 2.1 – not yet on desktop version of WebKit :
web application with a manifest – defined per the HTML5 spec – will be saved with any cached resources.
A cross-platforms and cross-browsers wrapper, ActiveRecord.js, allows to manage transparently (using the same APIs) access to data from a RDA javascript application, whatever underlying implementation : in js memory or database (through adaptors for Jaxer MySQL, Jaxer SQLite, Adobe AIR, Google Gears, and HTML5 Javascript database support).
