Rules-Based Rapid Application Development (RBRAD)
WebObjects features a set of rapid development technologies that can automatically create a Web application without the need to write any Java code. Given a model file for a database, WebObjects will create an interface supporting nine common database tasks, including querying, editing and listing. Such applications are useful for prototyping or administering a database, perhaps to check relationships or to seed the database with data.
The user interface is generated dynamically, on-the-fly at runtime using a rules-based system—no code is generated. Consequently, one can modify an application's configuration at runtime (using an assistant program) without recompiling or relaunching the application.
Developers can utilize one of three different technologies, depending upon the type of interface they wish to employ:
- Direct To Web (D2W) allows developers to rapidly create an HTML-based Web application that accesses a database.
- Direct To Java Client allows developers to rapidly create a client desktop application using the Java Swing toolkit. An advantage of Java Client applications is that they can take advantage of the processing power of the client computer to perform operations such as sorting a list of items received from the server.
- Direct To Web Services allows developers to rapidly develop Web service-based applications that provide access to a data store.

Famous quotes containing the words rapid, application and/or development:
“But parents can be understanding and accept the more difficult stages as necessary times of growth for the child. Parents can appreciate the fact that these phases are not easy for the child to live through either; rapid growth times are hard on a child. Perhaps it’s a small comfort to know that the harder-to-live-with stages do alternate with the calmer times,so parents can count on getting periodic breaks.”
—Saf Lerman (20th century)
“It would be disingenuous, however, not to point out that some things are considered as morally certain, that is, as having sufficient certainty for application to ordinary life, even though they may be uncertain in relation to the absolute power of God.”
—René Descartes (1596–1650)
“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (1848–1925)
