ActiveRecord.js 是一个开源的JavaScript 对象映射框架，包括：
Google Gears (client-side persistence)
In Memory (if no SQL server is available on the client)
Adobe AIR (client-side persistence)
SQLite and MySQL (via Aptana Jaxer, the open source Ajax server)
additional environments (like HTML5) expected to come through working with the community on the project
ActiveRecord.js abstracts away underlying SQL commands so that JavaScript developers can have a unified API for storing, finding, selecting and retrieving objects and their data using the ActiveRecord pattern popularized by the Ruby on Rails community.
