qcl is a set of interoperating client-server JavaScript and PHP libraries that are useful for web application development.

The qooxdoo-style frontend library can be used with any backend (it is not tied to the PHP json-rpc server) and provides common functionality (authentication, clipboard, databinding) for the client application, including prebuilt ui widgets.

The PHP backend extends the PHP JSONRPC server, implementing the following technologies for PHP5:

• Object and models with properties that behave similar to the qooxdoo property system.
• Controller-Model architecture (the data is sent to the frontend for the "View" part of the MVC design pattern)
• Object Persiststence
• Active Record Pattern / Object-Relational Mapping(ORM) including automatic property management and fully automatic relational database table setup and update. DB tables are automagically synchronized with the property and relation schema.
• Fully abstracted table associations: Models are linked programmatically - no "JOIN" queries are necessary at all.
• Interacting with the user through dialogs initiated from the server (reversing the request-response model)
• Integration with QxTransformer, a toolkit for writing qooxdoo GUIs with an xml-based declarative syntax ("XUL for qooxdoo").
• Plugin system for server-side PHP and client-side javascript classes which are loaded on demand only.
