Abstract: A portable business language and automated software development system comprises one or more servers containing a set of requirement inputs and an application engine residing on at least one of the one or more servers. The application engine comprises a requirements input component receiving a subset of the set of requirement inputs, a compiler component transforming the subset of the set of requirement inputs into one or more machine-readable codes, and a preparation component. The preparation component uses one of the one or more machine-readable codes to prepare a user interaction device to execute a final application, prepare a memory of the one or more servers to store data that may be provided by a user of the user interaction device, and transform the one or more machine-readable codes into an interpreted platform-specific code having additional parameters that customize the interpreted platform-specific code for the platform.
