7. The computer-implemented system according to claim 1 , wherein the defined document is written by XML (Extensible Markup Language), the machine readable interface generator engine includes a XML interface generator engine, and the machine readable interface document is represented by XML, and the source code generator engine includes XSL (Extensible Stylesheet Language) code generation engine.
1. A computer-implemented system for integrating at least one analytical or modeling driver into an existing business analytic environment, the system comprising: at least one memory device; at least one processor connected to the memory device; a BAMS (Business Analytics and Mathematical Sciences) driver, implemented on the memory device and run by the processor, for loading a real database driver associated with a database and redirecting a request from a client application to the real database driver; an extension driver, invoked by the BAMS driver, for providing an interface to a data modeling or processing software and for converting the interface from a software environment compiled by a programming language to another software environment targeted to another programming language, and said extension driver manipulating the request before redirecting the request to the real database driver and post-processing results from the real database driver, the extension driver extending or overriding functionalities of the BAMS driver; the data modeling software configuring said processor to run multiple scenarios over the request if the results cannot be found in the database, wherein implementing the BAMS driver and the extension driver in the existing business analytic environment do not require any change made on the existing business analytic environment.
