A rich API Used for programming of single-page Web applications and Web applications synchronicity. Models and Views - The single most important thing that Backbone can help you with is keeping your business logic separate from your user interface. Collections - A Collection helps you deal with a group of related models, handling the loading and saving of new models to the server and providing helper functions for performing aggregations or computations against a list of models. View Rendering - Each View manages the rendering and user interaction within its own DOM element. If you're strict about not allowing views to reach outside of themselves, it helps keep your interface flexible — allowing views to be rendered in isolation in any place where they might be needed. Routing with URLs - In rich web applications, we still want to provide linkable, bookmarkable, and shareable URLs to meaningful locations within an app. Use the Router to update the browser URL whenever the user reaches a new "place" in your app that they might want to bookmark or share. Conversely, the Router detects changes to the URL — say, pressing the "Back" button — and can tell your application exactly where you are now.

* BlueBream is built on top of the Zope Tool Kit (ZTK), which has many years of experience proving it meets the demanding requirements for stable, scalable software. * BlueBream uses the powerful and familiar Buildout system written in Python. * BlueBream employs the Zope Object Database (ZODB), a transactional object database providing extremely powerful and easy to use persistence. * BlueBream registers components with Zope Component Markup Language (ZCML), an XML based configuration language, providing limitless flexibility. * BlueBream features the Zope Component Architecture (ZCA) which implements Separation of concerns to create highly cohesive reusable components (zope.component). * BlueBream implements Python Web Server Gateway Interface WSGI using Paste, PasteScript, and PasteDeploy. * BlueBream includes a number of well tested components to implement common activities.
