System and Method For Generating A Web Service Definition And Database Schema From Wireless Application Definition

Abstract

A system and method for generating a service interface definition for a data source from an application definition is provided. The system and method includes: a component processor for examining components forming a component based application, which include a screen component having screen definitions, to identify a screen control mapping identifying a transition between a source screen and a target screen. The system and method includes a service interface generation engine for generating a Web service definition for a Web service interface of a backend server of a data source, based on an operation definition describing an action supported by the data source. The operation definition is constructed based on the identified transition.
