Direct to Web Architecture

The Direct to Web framework works together with the WebObjects framework to generate web pages for nine database tasks including querying, editing, and listing. To do this, Direct to Web uses a task-specific component called a Direct to Web template that can perform the task on any entity. Direct to Web also translates the information that Enterprise Objects Framework provides about the entity into values the Direct to Web template needs to render the page.

This chapter discusses the Direct to Web architecture and how Direct to Web generates a page. More specifically, it describes

• the different types of components that Direct to Web uses to render the pages
• the Direct to Web context, an instance of the D2WContext class that resolves the bindings in the Direct to Web template's binding file
• the Direct to Web factory, an instance of the D2W class that creates the Direct to Web pages
• how Direct to Web generates a query page
• the Direct to Web rule system, which contains application configuration information
